Question

Choose the correct statement:
A. In an electrochemical cell a spontaneous chemical reactionproduces electric current B. In a redox reaction, the element with the lower reductionpotential will be oxidized C. In the electrolysis of aqueous sodium chloride, theproducts are chlorine gas and hydrogen gas D. the amount of metal deposited in an electrolysis reactiondepends on the amount of current, the length of time the currentflows and the molar mass of the metal.

Explanation / Answer

We Know that :     Among the given statements :        The  Option d is correct as per the faradays First law:          The amount ofsubstance deposited at the respective electrode is proportional toquantity of electricity passed and    amount of time taken.              m i x t               m = e x i x t                                            e - Electrochemical equivalent                                                                                                     =  Atomic weight / valency x 96500 F
