Explain what happens when an electric current is passed through a solution of aqueous silver trioxonitrate(v) |
|
Answer» Explanation: Faraday's second law of electrolysis states that, when the same quantity of electricity is passed through SEVERAL electrolytes, the MASS of the substances deposited are proportional to their RESPECTIVE chemical equivalent or equivalent weight. We know that, Equivalent weight of Ag = 1 108
=108 Equivalent weight of CU = 2 63.5
=31.75 Now as per Faraday's second law, Eq.wt.ofCu Eq.wt.ofAg
= MassofCu deposited MassofAg deposited
⟹ 31.75 108
= W 15.28
⟹W= 108 15.28×31.75
=4.49g |
