What is the amount of chlorine evoled when `2` amperes of current is passed for `30` minumtes in an aqueous solution of `NaCI` ?

Options

A. ` 66 g`
B. ` 33 g`
C. ` 1.32 g`
D. ` 99 g`

Answer

C

Explanation

At anode ` Cl^(-) rarr 1/2 Cl_2 + e^(-)`
` E_(Cl_2) = (35 . 5 xx 2)/2 = 35 .5`
`W_(Cl_2)= (E_(Cl_2)xx lxx t)/(96500) = (35.5 xx2 xx 30xx60)/(96500) = 1 32 g`.
