Question

when electric current is passed through copper sulphate solution,the copper deposits on the electrode connected to
a) Positive terminal of battery
b) Negative terminal of battery
c) Any terminal
d) None of these​

Answer 1

Answer:

Answer: The rod of impure copper plate should be connected to the positive terminal of the battery. Because when electric current is passed through the copper sulphate solution it dissociate into copper and sulphate ions. The free copper drawn to the negative terminal of the battery and get deposited on it.

Answer 2

Answer:

B) negative terminal of battery.

Explanation:

when we connect the impure cu at positive terminal

i. e. Anode then the cu²+ ions dissolves in the CuSO4, which is used as electrolyte for purifying impure cu and then finally the cu deposit on negative terminal

i. e. Cathode. Also the equal amount of cu²+ ions from copper sulphate ( electrolyte) deposits on negative terminal(cathode)...
