Question
Explain Faraday’s second law of electrolysis
Advertisements
Solution
Explanation:
Two cells are connected in series. They contain different electrolytes. Same quantity of
electricity is passed through them. In other words, the number of moles of electrons passed
through two electrolytes is same.
Moles of A produced in one cell = moles of electrons actually passed × mole ratio of A half
reaction
Mole of B produced in other cell = moles of electrons actually passed × mole ratio of B half
reaction
Hence, `"moles of A produced"/"moles of B produced" = "mole ratio of A half reaction"/"mole ratio of B half reaction"`
