Answer to Question #170169 in General Chemistry for ben

Question

0.5 mol of a cation required 144 750 C of electricity to be completely discharged. Calculate the charge on the cation.?

Answer 1

The quantity of electricity required to discharge 1 mole of univalent ion is approximately 96500 C

If 0.5 mol: 0.5*96500=48250 C;

144750/48250= 3

Answer: the charge is 3+
