It is desired to obtain 1.12 cc of hydrogen per second under STP condition from the electrolysis of acidulated water. Calculate the mount of current need to be passed?

A

`1.93A`

B

`9.65A`

C

`19.3A`

D

`0.965A`

Text Solution

Verified by Experts

The correct Answer is:
B

No. of moles of `H_(2)=112/22400`
No of equivalence of hydrogen
`=(1.12xx2)/22400=10^(-4)`
No . Of Faradays required `=10^(-4)`
`:.` Current to be passsed in one second
`=96500xx10^(-4)`
`=9.65A`

In the electrolysis of acidulated water, it is desired to obtain 1.12 cc of hydrogen per second under STP condition. The current to be passed is:

A 1-KW motor pumps out water from a well 10m deep. Calculate the quantity of water pumped out per second.

Electrolysis is the process in which electrical energy is converted to chemical energy. In electrolytic 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 propertional to the amount of charge passed through it. The mass of substance liberated at electrode is calculated using the following relation : m= ("ItE")/(96500) Here, E represents 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 one gram equivalent of the substance.
