Question

What current is to be passed for 0.25 s for deposition of a certain weight of a metal wch is equal to its electrochemical equivalent

Answer 1

the right answer is 2.458 ampere.....

Answer 2

Heyaaa mate,


● Faraday's First Law of Electrolysis -
- The mass of the substance (m) deposited or liberated at any electrode is directly proportional to the quantity of electricity or charge (Q) passed.
M = ZQ
M = ZIt

● Answer -
(a) 4 A


● Explaination -
# Given -
M = Z

# Solution -
According to formula -
M = ZIt
M = M × I × 0.25
I = 4 A

Therefore, 4 A current is passed for deposition of given metal.


Hope this helps you...
