Question

Determine the solubility of benzoic acid in water at different temperature and hence its heat of solution.

Answer 1

Answer:

Benzoic acid or benzene carbonic acid is poorly soluble in water.

Explanation:

Benzoic acid easily gets recrystallised though dissolved in water.

A room temperature i.e, at 20 degrees about 0.3 g of benzoic acid is soluble in 100 g of water.

When  the temperature is increased to 25 degrees then 0.34 g of benzoic acid id dissolved in 100 g of water.

When the temperature is increased to 100 degrees about 6.80 g of benzoic acid is dissolved in 100 g of water.
