sulphuric acid is mixed water to introduce ions in it so the conductance of the water increases which make the reaction faster. However it does not affect the chemical composition of the reactant or products, it only increases the speed of the reaction.
What is the role of dilute sulphuric acid in electrolysis of water?
Dilute sulfuric acid contains water. The ions present in this mixture are H + and OH – (from the water) and H + and SO 4 2– from the sulfuric acid. The H + ions are attracted to the cathode and the two negative ions are attracted to the anode but it is the OH – ion which loses electrons.
What is the function of dilute sulphuric acid?
In various concentrations the acid is used in the manufacture of fertilizers, pigments, dyes, drugs, explosives, detergents, and inorganic salts and acids, as well as in petroleum refining and metallurgical processes.
What is the function of dilute acid in electrolysis?
The electrolyte is dilute sulphuric acid (= acidified water) which, during electrolysis is split into hydrogen and oxygen gases.
Why is dilute sulphuric acid added to the distilled water?
Sulphuric acid (H2SO4) is added to water for electrolysis to make it dissociate in water completely so as to provide an increase in the conductivity of water. The water taken for electrolysis being distilled cannot dissociate it’s ions to conduct electricity.
