Question

what is the solubility of benzophenone with these: 5%HCL, NAHCO3 AND H2SO4

Answer 1

Benzophenone has structure

Benzophenone is an aromatic ketone.

Solubility of benzophenone:

1) In 5% HCl : Benzophenone will be insoluble in 5% HCl solution. In 5% HCl only amine get solublied as the solution is enough acidic (i.e. with enough protons) that protonates amino (-NH2 groug) and forms -NH₃⁺ which being charged get solvated in aqueous phase.

2) NaHCO₃ : Benzophenone will be insoluble in NaHCO₃ solution. In NaHCO₃ only acids with ionizable -COOH(carboxylic) group will be soluble as NaHCO₃ is weak base. As Benzophenone doesn't have such ionizable -COOH group it is insoluble in NaHCO₃ solution.

3) conc. H₂SO₄ : Benzophenone will be soluble in conc. H₂SO₄as it is strongly acidic able to prtonate carbonyl O in benzophenone making it a charged species and solvalizing it in aqueous phase.
