Question

assertion: a mixture of benzoic acid and naphthalene can be separated by crystallization from water reasoning: benzoic acid is soluble in hot water but naphthalene is insoluble in hot water​

Answer 1

Answer:

Benzoic acid is soluble in hot water but naphthalene is not soluble, hence separation can be carried out by crystallization in hot water.

A mixture of benzoic acid and napthalene can be seperated by crystallization form.

Answer 2

Both assertion and reason are true and the reason is the correct explanation of assertion.

• Crystallization is a separation method that takes advantage of variances in the solubility of the components in the solution. When the solubility of one or more components in a liquid is surpassed, crystallisation can occur.
• In this case, benzoic acid is soluble in hot water but naphthalene is insoluble in hot water. Hence, this way a mixture of benzoic acid and naphthalene can be separated by crystallization.
• Therefore, both assertion and reason are true and the reason is the correct explanation of assertion.
