Chemistry - GOC Question with Solution | TestHub

Picric acid, benzoic acid, dinitrophenol, squaric acid, $\mathrm{MeS}{\mathrm{O}}_3\mathrm{H}$ and ${\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4$ release $\mathrm{C}{\mathrm{O}}_2$ with $\mathrm{NaHC}{\mathrm{O}}_3$ because they are stronger acids than carbonic acid. Phenol and p-nitrophenol are bicarbonate-negative in this qualitative test; $\mathrm{N}{\mathrm{H}}_3$ and $\mathrm{C}{\mathrm{H}}_4$ do not qualify. Total: 6.
