Question

One gram equivalent of a substance is liberated at an electrode by:

• A. $6.023\times {10}^{23}electrons$
• B. $96500C$
• C. $1amp$ current for $1$ second
• D. $1amp$ current for $96500$ sec

Answer 1

Answer: (A), (B), (D)

The correct options are
A $6.023\times {10}^{23}electrons$
B $96500C$
D $1amp$ current for $96500$ sec

1 eq of substance is liberated by $6.023\times {10}^{23}$ electrons.

These electrons have charge $=1.6\times {10}^{-19}\times 6.023\times {10}^{23}$ =96500 C

1 amp current for 96500 sec have charge$=1\times 96500$ = 96500 C
