`500mL` of `1N` solution of `CuCl_(2)` was electrolyszed with a current fo 2 amperes for 1 hour. What is the normality of the remaining `CuCl_(2)` solution ?

Options

A. `0.85`
B. `0.15`
C. `0.30`
D. `1.0`

Answer

a

Explanation

Initial `mEq` of `Cu^(2+)=500xx1.`
Electricity passed `-=(2xx3600)/(96500)=0.746Eq`
`-=746mEq`
`mEq` of `CuCl_(2)` remaining `-=500-74.6=425.4mEq`
`:. N=(425.5)/(500)=0.85`
