Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Question

solute. The amount is often expressed in solubility curves like the one below. Interpret the following graphs to
Is solubility. The solubility is the amount of solvent that is dissolved in a given
forces. We often use the phrase like dissolves like A solvent like water can only dissolve a certain amount or
amount of sSolvent. Whether something dissolves denends on whether or not they have similar intermolecular
