(C) The reactivity of a metal towards an acidic solution depends on its standard reduction potential $(E^\circ)$.For the reaction $2Ag(s) + 2H^+(aq) \rightarrow 2Ag^+(aq) + H_2(g)$,the standard cell potential $(E^\circ_{cell})$ is calculated as $E^\circ_{cathode} - E^\circ_{anode}$.Here,$E^\circ_{H^+/H_2} = 0.00 \ V$ and $E^\circ_{Ag^+/Ag} = +0.80 \ V$.$E^\circ_{cell} = 0.00 \ V - 0.80 \ V = -0.80 \ V$.Since the $E^\circ_{cell}$ is negative,the reaction is non-spontaneous.Therefore,silver does not react with acidic solutions to evolve hydrogen gas.
