Vedclass · Answer

(C) $H_3PO_4$ is a triprotic acid $(K_{a1}, K_{a2}, K_{a3})$.During titration with $NaOH$,buffers are formed in the regions where the acid and its conjugate base coexist.$1$. The first buffer region is formed between $H_3PO_4$ and $H_2PO_4^-$.$2$. The second buffer region is formed between $H_2PO_4^-$ and $HPO_4^{2-}$.Therefore,a total of $2$ buffer regions are formed during the titration.

What is the total number of buffers formed during the titration of $H_3PO_4$ with $NaOH$?
