What is the like dissolves like rule in solubility?

The rule of thumb is that “like dissolves like”. Polar/ionic solvents dissolve polar/ionic solutes and non-polar solvents dissolve non-polar solutes. 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.

How does the statement like dissolves like apply to the basic principles of solubility?

A popular saying used for predicting solubility is “Like dissolves like.” This statement indicates that a solute will dissolve best in a solvent that has a similar chemical structure; the ability for a solvent to dissolve various compounds depends primarily on its polarity.

What does the phrase 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.

What are the 4 factors affecting solubility?

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 does’like dissolves like’mean in chemistry?

Polar solutes dissolve in polar solvents. “Like dissolves like ” means if any substance is polar then polar and ionic substances will be dissolved in it. Example : HCl in water. If the solvent is non-polar then the non-polar substances only can be dissolved in it.

Which is an example of a solvent that 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. Oil is non polar. Water will not dissolve oil. Water is polar. Salt NaCll) is ionic (which is considered extremely polar).

Why is the ” like dissolve like ” rule important?

As a further point, when soap is added to water it allows non polar molecules like greases and fats to be dissolved as the soap molecules contain a large polar head which is attracted to water and long non polar ‘tails’ which can dissolve the grease. Its is very important saying in chemistry that “ like dissolves like”.

Can a polar solute dissolve in a non polar solvent?

In basic terms, the rule says that most typically, polar solutes can dissolve in polar solvents and non-polar solutes can dissolve in non-polar solvents. But, polar solutes rarely dissolve in non-polar solvents and vice versa.
