In a given sample of bleaching powder `(CaOCl_(2).H_(2)O)` the percentage of available of chlorine is 49 .The volume in liters of chlorine obtained if 39gm of the sample is treated with HCl at NTP is

In a given sample of bleaching powder, the precentage of avilable chlorine is 49. The volume in litres of chlorine obtained if 20 g of the sample is treated with HCI at NTP is.

The percentage of available chlorine in a commercial sampleof bleaching powder is

What is the maximum percentage of available chlorine in a sample of bleaching powder ?

What is the percentage of chlorine in a good sample of bleaching power?

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

In textile industry, the cotton cloth is mainly bleached with the help of bleaching power. 3.55 g of bleachig power when treated with acetic acid and excess of KI liberated iodine which required 60 mL of 0.5 N sodium thiosulphate solution. The percentage of available chlorine in the sample is

Bleaching powder is obtained by treating chlorine with
