A current of 9.65 A is passed for 3 hours between platinum electrodes immersed in 0.5 dm^(3) solutionof concentration 2 mol dm^(-3) Ni(NO_3)_2. The molarity of solution after electrolysis would be

Answer»

0.46 M
0.91 M
`1.25M `
`0.625 M`

Solution :`96500 to(1)/(2), 9.65 XX 3 xx 60 xx 60 to n =?`
` n =0.54 ` LIBERATED , `[Ni^(+2)]_("new") = ((1-0.54))/(0.5) = 0.92 M`
