When Potassium chlorate is heated strongly it decomposes to give oxygen. But if a catalyst like manganese dioxide is mixed with it, oxygen is liberated at much lower temperature, in much shorter time. Potassium chlorate and manganese..

1) K 2 Cr 2 O 7 is soluble in not water. 2) It is in the form of orange crystals. 3) On heating potassium dichromate decomposes and forms potassium chromate and chromic oxide...

Laboratory Preparation of Oxygen - Any of the above mentioned methods could be used to prepare oxygen in the laboratory. Mercuric and silver oxides are not used for the preparation of oxygen, as they are very expensive...

1. It is a pale yellow powder. It has strong smell of chlorine. It is soluble in water but a clear solution is never formed due to the presence of impurities. 2. On long standing it undergoes auto-oxidation into calcium chlorate and calcium chloride. 4. On account of the fo..

Sodium carbonate is a white crystalline solid, which can exists as anhydrous salt (Na 2 CO 3 ), monohydrate salt (Na 2 CO 3 .H 2 O), heptahydrate salt (Na 2 CO 3 .7H 2 O) and decahydrate (Na 2 CO 3 .10H 2 ..

Beryllium halides are covalent while all other halides are ionic and are readily soluble in water. BeCl 2 is relatively low melting solid and volatile while others have high melting points. BaCl 2 has very high melting point. BeCl 2 is soluble in organic sol..

Some of the synthetic detergents have very low biodegradability. They are resistant to bacterial attack and are not fully degraded in sewage treatment units. Therefore, they cause water pollution when they are discharged into a river or any other water body. Phosphate salts present in synthetic de..
