To recognize acid and glycerin, we use copper (II) hydroxide, we have the following reactions:
2CH3COOH + Cu (OH) 2 = (CH3COO) 2Cu + 2H2O (When copper hydroxide is added to acetic acid, the solution becomes transparent).
C3H5 (OH) 3 + Cu (OH) 2 = C3H5OHCuO2 + 2 H2O (When copper hydroxide is added to glycerin, the solution becomes bright blue).
