Rahul went with his father to buy hinges for the door. The shopkeeper showed two types of hinges: normal iron hinges and the galvanised hinges. The normal hinges were cheaper while the galvanised hinges were costlier. Rahul's father opted for the cheaper normal iron hinges. Rahul suggested father to buy galvanised hinges though they were costlier. What was the rationale for Rahul to buy galvanised hinges?

A Galvanic cell consits of three compartment as shown in figure. The first compartment contain ZnSO_4 (1M) and III compartment contain CuSO_4 (1M). The mid compartment contain NaNO_3 (1M). Each compartment contain 1L solution: E_(Zn^(2+)//Zn)^(@)=-0.76 , E_(Cu^(2+)//Cu)^(@)=+0.34 , The concertation of Zn^(2+) in first compartment after passage of 0.1 F charge will be:
