What is the amount of chlorine liberated when

2 \mathrm{~A}

of current is passed for 60 minutes in an aqueous solution of

\mathrm{NaCl}

?

Options

A $2.507 \mathrm{~g}$
B $1.364 \mathrm{~g}$
C $2.648 \mathrm{~g}$
D $3.469 \mathrm{~g}$

Correct answer

C. $2.648 \mathrm{~g}$

Step-by-step solution

According to Faraday's law, w=

\frac{Z \text{ it }}{n F}=\frac{35.5}{96,500} \times

2

\times \frac{3600}{1}=

2.6487

\mathrm{~g}
