CHAPTER 24 : CHEMICAL EFFECTS OF ELECTRIC CURRENT When electric current flows through water (acidulated for better conduction ) then Hydrogen gas is found to be liberated at the cathode, while oxygen gas is liberated at the anode. This process of separating compounds into ions is called electrolysis. Solutions which are decomposed due to current passed through them are called electrolytes.
24.1 Faraday's Laws of Electrolysis First Law The amount (mass ) of a substance in an electrolyte liberated in electrolysis is proportional to the charge passed through the electrolyte. i.e, m µ Q or m = e Q .........(1) where e is called e.c.e. i.e. electro chemical equivalent of the substance. Second Law
If i.e. the same charge is passed through a number of electrolytes, then the mass of the substances liberated by electrolysis are in the same ratios as their chemical equivalents. i.e. m1: m2 : m3 : : C1 : C2 : C3
where C1 , C2 , C3 are the chemical equivalents. ********** |
