(A) In the nitration of benzene,the mixture of concentrated $HNO_3$ and concentrated $H_2SO_4$ is used.Here,$H_2SO_4$ acts as a stronger acid and protonates $HNO_3$ to generate the electrophile $NO_2^+$.The reaction is as follows:$HNO_3 + H_2SO_4 \rightleftharpoons H_2NO_3^+ + HSO_4^-$$H_2NO_3^+ \rightleftharpoons H_2O + NO_2^+$Since $HNO_3$ accepts a proton from $H_2SO_4$,it acts as a base in this reaction.
