Question

A current of 16 ampere flows through molten NaCl for 10 minute. The amount of metallic sodium that appears at the negative electrode would be

• A. 0.23 gm
• B. 1.15 gm
• C. 2.3 gm
• D. 11.5 gm

11.5 gm

Answer 2

By using m = zit $= \frac{A}{VF}$ it

⇒ $m = \frac{23}{1 \times 96500} \times 16 \times 10 \times 60 = 2.3gm$
