Calculate the charge in coloumbs required for oxidation of 2 moles of water to oxygen ? (Given 1 F=96,500 C `mol^(-1)`)

Text Solution

Verified by Experts

The oxidation reaction is :
`underset(2"mol")(2H_(2)O)to4H^(+)+O_(2)+underset(4F)4e^(-)`
Change in coloumbs (Q)`=4F=4xx(96500" C")=386000" C"`
