Calculate the deposited mass of silver which is plotted against charge in electrolysis of silver nitrate. Slope of the line gives:
Options
- AThe equivalent mass of silver
- BElectrochemical equivalent of silver
- CThe value of Faraday
- DThe current passed through the cell
Correct answer
B. Electrochemical equivalent of silver
Step-by-step solution
According to Faraday's 1 st law of electrolysis. W ∝ Q W = Z . Q ∵ Z = E F then W = Q E F or E F . Q Compare with straight line equation Y = mx + c [ m = slope of line] ∵ c = 0 , passing through origin Slope of the line m = E F = Z (Electrochemical equivalent of silver) Slope = E F
