Electrolysis in hindi-Electrolysis is a chemical effect of electric current. When an electric current is passed through pure metals, they अपघटित (decompose) But some substances are such that they decompose when an electric current is passed through them.
substances that when an electric current is passed decomposed are and chemical effect reflect, electrolyte are called. Like acid water, salt solution in water, etc., negative and positive ions are present in the electrolyte and the flow of electric current is due to the movement of these ions.
electrolyte Two plates are immersed in this solution, which are called cathode and anode.
Faraday’s first law of electrolysis
electrolysis The amount of matter liberated at an electrode is directly proportional to the total charge flowing through it.
If a current of i ampere is passed for a period of time, the amount of substance liberated is mass m yes then-
•m=Sit where z is a constant called the value of the released element. Electrochemical equivalents it is said.
of an element Electrochemical equivalents It is the mass of an element that is liberated when a current of 1 ampere is passed through it for 1 second.
Faraday’s second law of electrolysis
If the same current is passed through different electrolytes for the same time, then the mass of the elements liberated will be Chemical equivalent are sequentially proportional.
If the masses of the freed elements m1 and m2
And if their chemical equivalents are W1 and W2-
Faraday number in hindi—
Faraday number is the amount of charge that is liberated by electrolysis of one kg equivalent of an element. its value 9.65 x 10 ^ 7 coulombs per kg, is equivalent.
