Column I |
Column II |
Description |
|
(A) Electrochemical equivalent |
(ii) Mass of substance deposited by one coulomb of charge |
The mass of a substance that is deposited or evolved at an electrode during electrolysis when a unit quantity of electric charge (1 coulomb) passes through the electrolyte. |
|
(B) Faraday |
(iii) Charge carried by one mole of electrons |
A unit of electric charge equal to the charge carried by one mole of electrons. It is named after Michael Faraday, who discovered electrolysis. |
|
(C) Ampere |
(iv) One coulomb of electric charge passed through one second |
The unit of electric current. It is defined as the flow of one coulomb of charge per second. |
|
(D) Electrical energy |
(i) (\text{Potential difference } x \text{Quantity of charge}) |
The work done by electric charge. It is measured in joules. |
The correct answer is (2) A-ii, B-iii, C-iv, D-i.
