preparation of oxygen.. using potassium chlorate and manganese dioxide?

Question

pls explain... need badly..

Answer 1

Potassium chlorate is a compound containing potassium, chlorine and oxygen, with the chemical formula KClO3. In pure form, it is a white crystalline substance. It is the most common chlorate in industrial use, and is usually present in well-stocked laboratories. It is used



as an oxidizing agent,

to prepare oxygen,

as a disinfectant,

in safety matches, and

in explosives and fireworks.

Potassium chlorate ( KCLO3 ) decomposes upon heating to yield Potassium chloride and Oxygen Gas .

Manganese dioxide ( MnO2 ) is mixed with Potassium chlorate and performs as the catalyst of this reaction .

2 KClO3 ----( Heat with MnO2 Catalyst )----> 2 KCl + 3 O2

Answer 2

Potassium chlorate ( KCLO3 ) decomposes upon heating to yield Potassium chloride and Oxygen Gas .



Manganese dioxide ( MnO2 ) is mixed with Potassium chlorate and performs as the catalyst of this reaction .



2 KClO3 ----( Heat with MnO2 Catalyst )----> 2 KCl + 3 O2





Note :

1. Please also have a look at my other answers ( in My Profile )

2. I made a mistake at the beginning of my answer

" ( KCLO3 ) " should be corrected to " ( KClO3 ) "

Answer 3

Oxygen is given off, Potassium Chloride & unchanged manganese Dioxide remain. The MnO2 is the catalyst.
