Question 1 Report

Copper sulphate solution is electolysed using platinum electrodes A. current of 0.193 amperes is passed for 2hrs. How many grams of copper are deposited? (cu = 63.5, F = 96500 coulombs)

0.457g

0.500g

0.882g

0.914g

1.00g

Answer Details

Time = 2hrs 120mm = 120 x 60secs

current = 0.193amps

Quantity of electricity = 120 x 0.193

= 60 x 23.16

96,500 deposits 63.5 gms of Cu

60 x 23.2 will deposit $\frac{63.5 \times 60 \times 23.2}{96500}$

= 0.457
