Question

Calculate the solubility of the solute, if x g of solute is present in Y g of saturated solution at a given temperature .

Answer 1

1. The maximum amount of a solute in grams , which can dissolve in 100 g of a solvent at a given temperature is called solubility.

2. The amount of solute dissolved in a definite quantity of a solvent depends upon the nature of the solute & nature of the solvent .

3. It is given that

mass of solute = x g

mass of the solution = y g

$$\begin{gathered} \text{∴ ( y - x )g of solvent contains x g of solute.} \\ \text{Therefore 100g of solvent contains =}\frac{solute}{solvent}x100 \\ \left(Solubility\right)=\frac{x}{y-x}x100 \\ =\frac{100x}{y-x} \end{gathered}$$

The solubility of the solute at the given temperature is $\frac{100x}{y-x}$.
