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. ` 1. 32 g`
C. ` 33 g`
D. ` 99 g`

Answer

B

Explanation

At anode ` Cl^- rarr 1/2 Cl_2 + e^9-`
` E_(Cl_2) = (35.5 xx 2)/2 = 35.5`
` W_(Cl_2) = (E_(Cl_2) xx Ixx t)/(96500)`
`= (35 . 5 xx 2 xx 30 xx 60 )/( 96500) = 1.32 g`.
