1.	(a) Which solution is used for the leaching of silver metal in the presence of air in the metallurgy of silver ? (b) Out of C and CO, which is a better reducing agent at the lower temperature rangein the blast furnace to extract iron form the oxide ore ?
Answer» (a) Dilute solution of NaCl and KCN is used for leaching of silver metal in the presence of air in the metallurgy of silver. (b) Out of C and CO, Cois a better reducing agent at the lower temperature range because `DeltaG_((CO,CO_2))lt DeltaG_((Fe,FeO))`. So, CO will reduce FeO, will its self be oxidised to `CO_2`.
