Electrolysis of dilute aqueous NaCl solu...

Electrolysis of dilute aqueous NaCl solution was carried out by passing 10A current. The timerequired (in seconds ) to liberate 0.01 moles of `H_(2)` gas at the cathode is `: [ 1F =96500C ]`

Text Solution

Verified by Experts

The correct Answer is:
193
`2H^(+)+2e^(-)rarrH_(2)" "rArr" 1 mole "H_(2)="2 mole "e^(Theta)`
`"0.01 mole of "H_(2)="0.02 mole "e^(Theta)`
`0.02=(Q)/(F)=(Ixxt)/(F), " "t=(0.02xx96500)/(10)="193 sec"`
