\(\ce{MnO4^- (aq) + Y + 5Fe^2+ (aq) -> Mn^2+ (aq) + 5Fe^2+ (aq) + 4H2O (l)}\)
In the equation above, Y is:
\(5\mathrm{H^+}_{(aq)}\)
\(4\mathrm{H^+}_{(aq)}\)
\(10\mathrm{H^+}_{(aq)}\)
\(8\mathrm{H^+}_{(aq)}\)
Given that M is the mass of a substance deposited during electrolysis and Q is the quantity of electricity consumed, then Faraday's first law can be written as [Electrochemical equivalent]
\(M = \dfrac{E}{Q}\)
\(M = EQ\)
\(M = \dfrac{Q}{E}\)
\(M = \dfrac{E}{2Q}\)
