How long will it take to deposit eleectrolyically voltsmeter127 g of copper on the copper on the cathode of a copper voltameter by a currect of 50 A?
`("ECE of copper= "0.0003294g//C)`

How long will it take to deposit electrolytically 10.79 g of silver on the cathode of a silver voltameter by a current of 25 A ? (ECE of silver= 0.001118 g C^(-1) ).

A metal surface of surface area 250 cm^(2) is to coated onboth sides with copper by eletrolysis .How long will it take to deposit copper lauyer 0.01 cm in thick if a currect of 1.5 A is used ECE of copper =0.0003gC^(-1) and density of copper =9 g cm^(-3)

How much copper can be obtained from 100g of copper sulphate ?

Find the strengh of currect that deposited 0.777 g of matallic copper in half an hour in a copper voltameter .The atomic mass of copper is 63 and ECE of hydrogen is 0.00001036 g C^(-1)

The quantity of electricity needed to deposit 127.08 g of copper is :

How long will it taje 5 ampere of current to deposit 2 g of copper from a solution of copper sulphate ? (Given : CE of copper =32, F=96500 coulomb)

State and explain Faraday's laws of electrolysis. 0.2015g of copper were deposited by a current of 0.25 A in 45 min. What is the ECE of the copper?
