What mass of metal will stand out from the silver nitrate solution in 30 minutes at a current of 0.02A?

To solve the problem, we will use the formula of the combined law of Faraday electrolysis:

m (metal) = (M (metal) * I * t) / (F * Z), where:

M (metal) – molar mass, g / mol;

I – current strength, A;

t is the electrolysis time, s;

F is the Faraday electrolysis constant 96485 C / mol;

Z is the valence of the metal.

t = 30 * 60 = 1800 s;

m (Ag) = (108 * 0.02 * 1800) / (96485 * 1) = 0.04 g.

Answer: m (Ag) = 0.04 g.
