Question

Fairly concentrated solution of $AgN{O}_3$ weighing $108g$ is electrolyzed using $0.1F$ of electricity. The weight of resulting solution is:

• A. $94g$
• B. $11.6g$
• C. $97.2g$
• D. None of these

Answer 1

The correct option is C $97.2g$

As we know, $1F$ deposits one equivalent weight of compound so $0.1F$ will deposit $10.8gm$ of $AgN{O}_3$ so weight of remaining solution is $108-10.8=97.2$ gm.
