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`

Text Solution

Verified by Experts

The correct Answer is:
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%`

0.96 g of HI were heated to attain equilibrium 2HIhArrH_(2)+I_(2) . The reaction mixture on titration requires 15.7mL of N//10 hypo solution. Calculate degree of dissociation of HI .

Bleaching power is a mixed salt of hydrochloric acid and hypochlorious acid. It has the formula, CaOCI_(2).H_(2)O . It is manuafactured by the action of chlorine on dry slaked lime at 40^(@)C . There is also a view that bleaching power is a mixture [Ca(OCI)_(2)+CaCI_(2).Ca(OH)_(2).H_(2)O] . The amount of chlorine obtained form a sample of bleching power by the treatement with excess of dilute acids or CO_(2) is called a available chlorine. A good sample of bleaching power constains 35-38% of available chlorine. On long standing, it undergoes auto-oxidation and the amount of acvailable chlorine decreases. The estimation of available chlorine is done volumetrically by (a) iodometric method or by (b) aresenite method. In textile industry, the cotton cloth is mainly bleached with the help of bleaching power. The percentage of available chlorine in commercial samples of bleaching poweder is usually between 35% and 38% . The low value is due to

A 7.1 g sample of bleaching powder suspended in H_(2)O was treated with enough acetic acid and KI solution. Iodine thus liberated required 80 mL of 0.2 N hypo solution for titration. Calcutale the % of available chlorine :
