Vedclass · Answer

(B) diprotic acid is an acid that can donate two protons ($H^+$ ions) per molecule in an aqueous solution.$H_3PO_4$ is triprotic as it can donate $3H^+$ ions.$H_2S$ is diprotic as it can donate $2H^+$ ions.$HClO_3$ is monoprotic as it can donate $1H^+$ ion.Therefore,the question as stated is slightly ambiguous regarding $H_3PO_4$. However,if we consider the definition of diprotic,$H_2S$ is strictly diprotic. Given the options,if the question implies compounds that can act as diprotic acids,$H_2S$ is the correct choice. If the question intended to ask for acids that are at least diprotic,both $(a)$ and $(b)$ would be considered. Based on standard chemistry nomenclature,$H_2S$ is the primary diprotic acid here.
