Question

10 g of bleaching power on reaction with KI required 50 mL of 2N hypo solution. Thus, `%` of bleaching poweder is
A. `100`
B. `80`
C. `63.5`
D. `35.5`

Answer 1

Correct Answer - C
`50 mL 2N` hyposolution `= 50 mL 2N I_(2)` soln
`=50 mL 2N CI_(2)` soln
`= 50 mL 2N CaOCI_(2)` solan
`= 6.35g CaOCI_(2)`
`= (6.35)/(10)xx100=63.5%`
