What is meant by available chlorine in bleaching powder?
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.
How is the available chlorine in bleaching powder estimated?
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
What happens when bleaching powder reacts with ammonia?
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)
What happens when chlorine gas is passed through lime water?
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
Preparation of 0.5 chlorine 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
What is the oxidation state of chlorine in bleaching powder?
In bleaching powder (calcium hypochlorite), the oxidation state of chlorine is +1.
Name the substance which on treatment with chlorine yields bleaching powder?
Calcium hydroxide, when treated with chlorine gas, yields bleaching powder, which is calcium hypochlorite.
Why does bleaching powder smell of chlorine in damp air?
When bleaching powder (calcium hypochlorite) is exposed to damp air, it reacts with water to release chlorine gas. This characteristic smell of chlorine gas is what you detect when using or opening a container of bleaching powder in damp conditions.
Why chlorine is better disinfector than bleaching powder?
Chlorine is better as a disinfectant than bleaching powder because it is more stable and has a higher concentration of available chlorine. This means that chlorine is more effective at killing bacteria and viruses. Additionally, chlorine is easier to handle and use in disinfection processes compared to bleaching powder.
What percentage of chlorine in fresh bleaching powder is?
Fresh bleaching powder typically contains around 35-40% of available chlorine. This percentage can vary slightly depending on the specific formulation and brand of bleaching powder.
Why do bleaching powder smell strongly like chlorine?
Bleaching powder, also known as calcium hypochlorite, releases chlorine gas when it reacts with water. The strong smell comes from this chlorine gas being released, which is reminiscent of the smell of chlorine in swimming pools.

What is the percentage of available chlorine bleaching powder?
Typically, the percentage of available chlorine in bleaching powder ranges from 30% to 35%. This is important to consider when using it for disinfection or bleaching purposes to ensure proper dilution and effectiveness.
Which element is responsible for bleaching in bleaching powder?
Chlorine is the element responsible for bleaching in bleaching powder, also known as calcium hypochlorite. When bleaching powder is dissolved in water, it releases chlorine gas, which has bleaching properties that help remove stains and disinfect surfaces.
What is the oxilation state of chlorine in bleaching powder caocl2?
The oxidation state of chlorine in bleaching powder (CaOCl2) is +1. This is because calcium has an oxidation state of +2 and oxygen has an oxidation state of -2, so the total charge must be balanced by the chlorine with an oxidation state of +1.
Why bleaching powder give a typical smell in air?
it gradually looses its color.
