What Does Like Dissolves Like Mean?

The rule of thumb is that “like dissolves like”. 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.

What does dissolve like mean chemistry?

NATURE OF SOLUTE AND SOLVENT. Polar solutes dissolve in polar solvents.

Non-polar solutes

dissolve in non-polar solvents. This is what we mean by the phrase. “Like Dissolves Like”

What does like dissolves like mean quizlet?

“Like dissolves like” means

polar solutes are more soluble in polar solvents and nonpolar solutes are more soluble in nonpolar solvents

. … A solute will be most soluble in a solvent that generates intermolecular forces similar in strength to its own.

Which of the following will dissolve most rapidly?

Where we use the phrase like dissolves like?

“Like dissolves like” is an expression

used by chemists to remember how some solvents work

. It refers to “polar” and “nonpolar” solvents and solutes. Basic example: Water is polar. … Like dissolves like, that means polar dissolves polar, so water dissolves salt.

What are the 5 factors affecting solubility?

• Temperature. Basically, solubility increases with temperature. …
• Polarity. In most cases solutes dissolve in solvents that have a similar polarity. …
• Pressure. Solid and liquid solutes. …
• Molecular size. …
• Stirring increases the speed of dissolving.

What is being dissolved in solution?

When one substance dissolves into another, a solution is formed. …

The solute

is the substance that is being dissolved, while the solvent is the dissolving medium. Solutions can be formed with many different types and forms of solutes and solvents.

What factors affect the dissolving rate of solutions?

The rate of dissolving depends on

the surface area (solute in solid state), temperature and amount of stirring

.

What occurs in a solvation?

In the process of solvation,

ions are surrounded by a concentric shell of solvent

. Solvation is the process of reorganizing solvent and solute molecules into solvation complexes. Solvation involves bond formation, hydrogen bonding, and van der Waals forces. Solvation of a solute by water is called hydration.

Which substance is present in large amount?

The substance that is present in the largest amount is called

the solvent

and the one present in the smaller amount is called a solute.

Why does mixing increase the speed at which a solid dissolves?

Stirring. Stirring a solute into a solvent speeds up the rate of dissolving

because it helps distribute the solute particles throughout the solvent

. For example, when you add sugar to iced tea and then stir the tea, the sugar will dissolve faster.

Is like dissolves like always true?

“

Like dissolves like” is generally true

, but a broad oversimplification. What dissolves/mixes with what depends on how the chemical/functional groups present in each compound interact. Polar and non-polar are generalized terms to describe how evenly electrons are distributed between different parts of a given molecule.

Is rubbing alcohol polar or nonpolar?

This is due to the fact rubbing alcohol also has a portion of its molecule that has no charges, and is

nonpolar

.

What are the 3 ways to increase solution rate?

If you are trying to dissolve a substance, you have three primary avenues to increase the dissolution rate:

decreasing the particle size of the solid, increasing the temperature and/or increasing the mixing or stirring rate.

What are 4 factors that affect solubility?

– Hence, we can conclude that the four factors which affect the solubility of ionic compounds are

common ion effect, temperature, solute-solvent interaction and molecular size

.

What are the 3 factors affecting solubility?

If Gases as a solute needs to be dissolved in a solvent, there are factors influencing solubility, such as

temperature, nature of solvent and solute, and pressure

.
