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

A

0.46 M

B

0.91 M

C

`1.25M `

D

`0.625 M`

Text Solution

Verified by Experts

The correct Answer is:
B
`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`

Electrolysis is the process in which electrical energy is converted to chemical energy. In electrolyte cell, oxidation takes place at anode and reduction at cathode. Electrode process depends on the electrode taken for electrolysis. Amount of substance liberated at an electrode is directly proportionation to the amount of charge passed through it. The mass of substance liberated at electrode is calculate using the following realation : m=(itE)/(96500) Here, E represent the equivalent mass and 96500 C is called the faraday constant. Faraday (96500 C) is the charge of 1 mole electron i.e., 6.023 xx 10^(23) electrons, it is used to liberate on gram equivalent of the substance.
