What is the electrochemical equivalent of a substance when 150 gm of it is deposited by 10 ampere of current passed for 1 sec?

Explanation

Given :
Amount of the substance deposited,
`" "m=150g`
current strength = 1 = 10 ampere
`" "Time=t=1sec`.
By Faraday.s first law,
Formula : m = ZIt
Solution : `therefore Z=m/(It)=150/(10 times 1)`
Electrochemical equivalent
`" "`= 15.0 gm `coloumb^(-1)`
