Question

the approximate time duration in hours to electroplate 30 gram of Calcium from molten calcium chloride using current of 5 ampere is explain it ​

Answer 1

let time =t sec

electricity passed=5×t

40 gram of calcium can be electroplated by electricity =96500×2C

30 gram of calcium can be electroplated by electricity =96500×2×30/40

=144750C

5t=144750

t=144750/5

=28950s

=8.04hrs
