13.2: Solutions- Homogeneous Mixtures [1]
– Explain the significance of the statement “like dissolves like.”. – Explain why certain substances dissolve in other substances.
The minor component of a solution is called the solute. By major and minor we mean whichever component has the greater or lesser presence by mass or by moles
However, here we will confine the discussion to solutions for which the major component and the minor component are obvious.. Solutions exist for every possible phase of the solute and the solvent
4.2: Overview of Extraction [2]
“Extraction” refers to transference of compound(s) from a solid or liquid into a different solvent or phase. When a tea bag is added to hot water, the compounds responsible for the flavor and color of tea are extracted from the grounds into the water (Figure 4.1a)
Bakers use the extract of vanilla, almond, orange, lemon, and peppermint in their dishes, essences that have been extracted from plant materials using alcohol (Figure 4.1b).. Figure 4.1: Examples of extraction: a) Tea, b) Baking extracts, c) Plant pigments extracted into water droplets after sprinklers hit a fallen leaf on the sidewalk.
A solution containing dissolved components is placed in the funnel and an immiscible solvent is added, resulting in two layers that are shaken together. It is most common for one layer to be aqueous and the other an organic solvent

It has partial positive and negative charges at opposite ends.. What type of solvent could remove sharpie marker from glass?
What does ‘Like dissolves like’ mean?A. The compounds that are from the same period on the periodic table will dissolve each other.B. Polar solutes dissolve in polar solvents.C. Nonpolar solutes disso [4]
The compounds that are from the same period on the periodic table will dissolve each other.. That compounds from the same family on the periodic table will dissolve each other.
‘like dissolves like,’ means that the chemical compounds with similar chemical features will dissolve one in another.. -Generally polar solvents have a habit to dissolve polar solutes and nonpolar solvents have a habit to dissolve nonpolar solutes.
-Take an example of glucose, it is an ionic substance nothing but polar. So, glucose dissolves in a polar solvent like water.
Explain the solubility rule “like dissolves like” in terms of intermolecular forces that exist in solutions. [5]
“Like dissolves like” term is used when the solvent dissolves in the solvent if its interactions between molecules are the same. This is because polar solutions can be dissolved in polar solvents and non-polar solute can be dissolved in non-polar solvents.
CBSE | Chemistry | Class 12 | Exercise 1 | NCERT Exemplar | Solutions. Explain the solubility rule “like dissolves like” in terms of intermolecular forces that exist in solutions.
Question 38 Explain the solubility rule “like dissolves like” in terms of intermolecular forces that exist in solutions. [6]
Explain the solubility rule “like dissolves like” in terms of intermolecular forces that exist in solutions.. If the intermolecular interactions are similar in both constituents, i.e., solute and solvent then solute dissolves in the solvent
Thus, the statement ‘like dissolves like’ proves to be true. e.g., non-polar organic compounds dissolve in non-polar organic solvent while polar inorganic compounds (salts) dissolve in polar solvent (water).
What is meant by the phrase like dissolves in like in chemistry [7]
Like dissolves like” is an expressionused by chemists to remember how some solvents work. It refers to “polar” and “nonpolar” solvents and solutes
Polar solvents dissolve polar solutes and non polar solvents dissolve non polar solutes.. Explain this statement clearly : “To call a dimensional quantity ‘large’ or ‘small’ is meaningless without specifying a standard for comparison”
The SI base units are the standard units of measurement defined by the International System of Units (SI) for the seven base quantities of what is now … known as the International System of Quantities: they are notably a basic set from which all other SI units can be derived. The units and their physical quantities are the second for time, the metre (sometimes spelled meter) for length or distance, the kilogram for mass, the ampere for electric current, the kelvin for thermodynamic temperature, the mole for amount of substance, and the candela for luminous intensity
Primary Connections: Linking science with literacy [8]
This topic is intended to follow Solutions and Talking solutions and looks at how liquid solvents and different solutes form liquid solutions. It would also help if you were familiar with the topic From atoms to molecules.
Polar/ionic solvents dissolve polar/ionic solutes and non-polar solvents dissolve non-polar solutes. For example, water is a polar solvent and it will dissolve salts and other polar molecules, but not non-polar molecules like oil
The rule mentioned above, “like dissolves like”, is a very handy way of determining which substances can be dissolved in which solvents.. Metals are generally not very soluble in the common solvents but non-metals, molecular compounds and ionic compounds are all soluble in at least one common solvent
Solubility [9]
In chemistry, solubility is the ability of a substance, the solute, to form a solution with another substance, the solvent. Insolubility is the opposite property, the inability of the solute to form such a solution.
For some solutes and solvents, there may be no such limit, in which case the two substances are said to be “miscible in all proportions” (or just “miscible”).[2]. The solute can be a solid, a liquid, or a gas, while the solvent is usually solid or liquid
Gases are always miscible in all proportions, except in very extreme situations,[3] and a solid or liquid can be “dissolved” in a gas only by passing into the gaseous state first.. The solubility mainly depends on the composition of solute and solvent (including their pH and the presence of other dissolved substances) as well as on temperature and pressure
Like Dissolves Like [10]
Can you imagine a cup of coffee, sugarless at the top but intensely sweet at the bottom? Likewise, imagine a bowl of soup without salt at the top but over-salted at the bottom. Would these be enjoyable? We owe the joy of uniformly sweetened coffee or perfectly seasoned soup, as well as several vital life processes, to “dissolution.”
A homogeneous mixture is uniform in composition and properties throughout. Pure substances, whether they are elements or compounds, are rarely found in nature
A mixture of sand and salt is not homogeneous, while a mixture of salt and water forms a homogeneous mixture (or solution) when enough water is added to dissolve all of the salt present. Likewise, gases dissolve in liquids to form solutions
The Solution Process [11]
Solutions are homogeneous mixtures of two or more pure substances. For our purposes, we will generally be discussing solutions containing a single solute and water as the solvent
That is to say if you had a liter of salt and 2 grams of water. In that case, the salt would be the solvent and the water the solute
When we do place solutes and solvents together, there is what we call the solution process. You can think of it as being similar to what you would experience if you tried to squeeze into an already packed elevator

Like dissolves like: A first-principles theory for predicting liquid miscibility and mixture dielectric constant [13]
Like dissolves like: A first-principles theory for predicting liquid miscibility and mixture dielectric constant. Supplementary material for this article is available at http://advances.sciencemag.org/cgi/content/full/7/7/eabe7275/DC1
However, despite their importance, miscibility is usually predicted qualitatively based on the vaguely defined polarity of the liquids, and the dielectric constant of the mixture is modeled by introducing mixing rules. Here, we develop a first-principles theory for polar liquid mixtures using a statistical field approach, without resorting to mixing rules
The dielectric constant predicted by this theory agrees well with measured data for simple binary mixtures. On the basis of the derived free energy of mixing, we can construct a miscibility map in the parameter space of the dielectric constant and molar volume for each liquid

Dissolving Process Study Guide [16]
Dissolution is the process in which soluble solute particles interact with solvent particles to create a solution.. We mix two substances to create a solution every day
To understand dissolution, we must first understand the events that occur at the molecular level during the process. The reason that a solute dissolves entirely in a solvent depends on the nature and characteristics of the solute
It is a common saying in chemistry that “like dissolves like.” This phrase stems from the fact that a solute and a solvent must have similar intermolecular forces to form a solution. The first step in the dissolving process is introducing a solute to a solvent
What is the meaning of the expressionlike dissolve like? [17]
“like dissolves like” means that polar solvents dissolve polar solutes, and that on-polar solvents dissolve non-polar solutes.. for example: water (a polar solvent) dissolves salt NaCl (polar solute, forms Na+ Cl-)
By contrast nonpolar and polar substances will not dissolve one another.. vinegar is acetic acid and if the lollipop is acidic then it will dissolve fast as like dissolve like..
Its intermolecular forces are incompatible with water’s, so polar water will not be able to dissolve it.. it stands for aqueous, meaning it is able to dissolve in water.

Solubility of one fluid (liquid or gas) in another may be complete (totally miscible; e.g., methanol and water) or partial (oil and water dissolve only slightly). In general, “like dissolves like” (e.g., aromatic hydrocarbons dissolve in each other but not in water)
Generally, solubilities of solids in liquids increase with temperature and those of gases decrease with temperature and increase with pressure. A solution in which no more solute can be dissolved at a given temperature and pressure is said to be saturated (see saturation)
