Question

When 100g of a saturated solution is evaporated at $50^{\circ} C$ , 50g of solid is left over. Find the solubility of the substance at $50^{\circ} C$

Open in App

Solution

Solid left over on evaporation is 50 g Solubility (S)
$= (W (s o l u t e) / W s o l v e n t) \times 100$ ............ (1)
Amount of solute $=$ 50 g ................ (2)
$W_{s o l u t i o n} = W_{s o l u t e} + W_{s o l v e n t}$
$\Rightarrow 100 = 50 + W_{s o l v e n t}$
$W_{s o l v e n t} = 50 g$ ............ (3)
Substituting (2) and (3) in (1), we get Solubility (S) $= (50 / 50) \times = 100$
