Calculate the time required for a current of 2 ampere to decompose one gram mole of water.

Text Solution

Verified by Experts

Mass of `H_(2) O = 1 g"mol" = 18 g `
Equivalent mass ( E ) of `H_(2) O = ( 18)/( 2) = 9 g`
`m = zit = ( E )/( 96500) xx i.t `
or `t = ( 96500xxm )/( E.i) = ( 96500xx18)/( 19 xx2 xx 60 xx 60) = 26.80h`
