Consider th following statement
I Q=lt
II charge is required for reductin or reduction depends on the stoichiometry of electrode reaction
III charge on 1 electron `=1.6021xx10^(-19)` C
IV charge on one mole of elctron `=1.6021xx10^(-19) C`
(V) Quantity of electricity is coulomb
VI 1F =96500 C `mol^(-1)` which of the statements (s) given above is /are incorrect ? choose the correct option

A

I and II

B

II and III

C

IV and V

D

VI and I

Text Solution

Verified by Experts

The correct Answer is:
B

Q=It
Q is in Columbs when l is in ampere and t is in second
charge on one electrone =`1.6021 xx1d0^(-19)` C
Charge on one mole of electron =`96487 C mol^(-1)`
`1 F = 96500 C mol^(-1)`
Quantity of electricity is called faraday
