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 ?

Text Solution

Verified by Experts

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.
