Question

A mixture of benzoic acid and benzoin is treated with sodium bicarbonate solution. After stirring with bicarbonate, in which form is benzoic acid now in solution?

Answer 1

Benzoic acid is now in the form of sodium benzoate.

Step-by-step explanation:

When a mixture of benzoic acid and benzoin is treated with sodium bicarbonate solution, the benzoic acid is converted into its more water-soluble ionic carboxylate form, sodium benzoate, which is then extracted into the aqueous layer. The reaction can be represented as follows:

PhCO2H(aq) + NaHCO3(aq) → PhCO2Na(aq) + H2O(l) + CO2(g)

So, the benzoic acid's solution is sodium benzoate.

I hope that helps!
