Vedclass · Answer

(B) Concentrated sulphuric acid $(H_2SO_4)$ acts as an oxidizing agent.Among the given metals,$Ag$ (silver) reacts with hot concentrated $H_2SO_4$ to form silver sulphate,sulphur dioxide,and water.The chemical reaction is:$2Ag + 2H_2SO_4 	o Ag_2SO_4 + SO_2 + 2H_2O$$Au$ (gold) and $Pt$ (platinum) are noble metals and do not react with concentrated $H_2SO_4$.$Pb$ (lead) forms a protective layer of $PbSO_4$ on its surface,which prevents further reaction.Therefore,the correct option is $B$.
