Vedclass · Answer

(B) Oxalic acid $(HOOC-COOH)$ is a dicarboxylic acid that acts as a reducing agent. It can reduce Tollens' reagent (ammoniacal silver nitrate solution) to metallic silver $(Ag)$.Tartaric acid $(HOOC-CH(OH)-CH(OH)-COOH)$ does not reduce Tollens' reagent.Therefore,ammoniacal silver nitrate solution can be used to distinguish between them.Both acids react with sodium bicarbonate to evolve $CO_2$ gas,and both turn blue litmus red,so these cannot be used for distinction.
