1.	A 200 W, 110 V in candescent lamp is connected in series with cells containing aqueous ZuCI . solution. What is the time required to deposit 1.109 g of metal ?
Answer» Solution :CURRENT strength in AMPERE `= "Watt/Volt"` `=200/110=1.818` Time `=1xx60xx60=3600` SEC, Quantity of electricity `=1.818xx3600` `=6545` coul. Zinc is divalent. 193000 coul are required to deposit 65.4 G of zinc. Weight of metal DEPOSITED using 6545 coul `=(6545xx65.4)/(193000)=2.219` g.
