(a) Explain the term electrodes in electric cells.
b) An electric current passing through an electrolyte for 2 minutes deposited 200 g of a substance. If the electrochemical equivalent of the substance is 8.33 x 10\(^{-4}\)g C\(^{-1}\), calculate the current passed.

Correct Answer: Option n
Explanation:
(a) An electrode is a conductor through which electrons flow into and out of the electric cell.
(b) I = \(\frac{M}{zt} = \frac{200}{8.33 \times 10^{-4} \times 60 \times 2}\)
