Question

What do you mean by the terms - solutions, solute and solubility.

Answer 1

Solution -

• A homogeneous mixture of two or more substances is called a solution.
• A solvent and a solute are components of the solution.
• Solution may be of different according to the solubility.
• Example - $$\begin{gathered} \mathrm{sugar}+\mathrm{water}\to \mathrm{sugar}\mathrm{syrup} \\ \mathrm{solute}\mathrm{solvent}\mathrm{solution} \end{gathered}$$

1. Homogeneous solution - These are solutions with the same composition and properties throughout the solution.
2. Heterogeneous solution - These are solutions with different compositions and properties throughout the solution.

Solute -

• The component of the solution that can be dissolved in the solvent and usually present in less quantity, is called the solute.
• The solute particles do not settle down when left undisturbed, so the solution is stable.

Example - $$\begin{gathered} \mathrm{salt}+\mathrm{water}\to \mathrm{salt}\mathrm{solution} \\ \mathrm{solute}\mathrm{solvent}\mathrm{solution} \end{gathered}$$

Solubility-

• The amount of solute that can be dissolved in a solvent is called its solubility.
• Solubility of the solvent increases with increase in temperature.
