An acid compound. Be very carefull: Chlorine is very VERY toxic gas.
Usually it relates to hypochlorites content in the product. Available chlorine is the quantity of chlorine that can hypothetically be produced by reaction of bleaching powder with hydrochloric acid. Greater the available chlorine is - greater oxidation ability the bleaching powder has. For example, available chlorine 5% means that fixed amount of something can be oxidized by (100/5)X=20X grams of bleaching powder and the same can be done with only X grams of pure chlorine.
Here are some methods used for discovering how much chlorine is in bleaching powder: Penot's method and Bunsen and Wagner's method. http://chemistry.proteincrystallography.org/article179.html
When chlorine is passed through dry slaked lime power Ca(OH)2 , bleaching powder is obtained .Slaked lime --- Ca(OH)2 Chlorine --- Cl2The chemical equn :- Ca(OH)2 + Cl2 ------> CaOCl2 + H2OCaOCl2 is bleaching powderThe three properties Of bleaching powder , (CaOCl2) areIt is a yellowish white powder with a strong smell of chlorineIt reacts with carbon dioxide , dil. HCl and di. H2SO4 to form chlorine gas.It is soluble in water but since it is generally contaminated with Ca(OH)2 , it may produce a milky solution
The following method will give 0.5% Chlorine solution Materials required: 1 litre water and 3 tsp bleaching powder.(see that it is 33.3% Chlorine) Add three teaspoon bleaching powder, make a paste with hand, after adding a small quantity of water.(there shall be no solids felt) Add remaining water. The resultant liquid will appear something like toddy. Now you have 0.5% Chlorine solution
when bleaching powder reacts with ammonia, nitrogen gas is evolved along with calcium chloride and water. The balanced reaction is: 3CaCl(OCl)(s)+2NH3(aq) = 3CaCl2(aq)+N2(g)+3H2O(l)
The oxidation state of chlorine in bleaching powder would be zero.
Bleaching powder is mostly chlorine so it smells like it. It has very strong bleaching (removing color) abilities and destroys most bacteria.
The quantity of chlorine released by a bleaching powder when treated with acid.
Usually it relates to hypochlorites content in the product. Available chlorine is the quantity of chlorine that can hypothetically be produced by reaction of bleaching powder with hydrochloric acid. Greater the available chlorine is - greater oxidation ability the bleaching powder has. For example, available chlorine 5% means that fixed amount of something can be oxidized by (100/5)X=20X grams of bleaching powder and the same can be done with only X grams of pure chlorine.
34% available chlorine-30%-40%
+1 and -1
30 -35
When carbon Di-oxide reacts with Bleaching powder it produces chlorine gas. That is why we do not use carbon Di-oxide for fighting the bleaching powder fire. A.K.Sharotri

On standing in the open air bleaching powder react with carbon dioxide produce chlorine gas. As a result the activity or bleaching property of bleaching powder is reduced. So it is kept in a closed container.
it gradually looses its color.
