potassium chlorate potassium chloride

A mixture of potassium chlorate (KClO 3 ) and manganese dioxide (MnO 2 ) (4 : 1) is heated in a dry test tube. The oxygen evolved is collected over water. The decomposition of KClO 3 is accelerated even at lower temperatures as MnO 2 acts as a catalyst...

Preparation of Oxygen - From Potassium Chlorate - 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. Pot..

Role of potassium, chloride and malate ions in stomatal opening (PEPcase = Phosphoenol pyruvate carboxylase) Levitt (1974) observed that proton (H + ) uptake by guard cells, chloroplasts takes place with the help of ATP. This leads to increase in value of pH in guard cells. Rise..

The common name of potassium nitrate is Bengal salt petre or nitre. It can be prepared by treating the oxide, hydroxide, carbonate or hydrogen carbonate salts of potassium with nitric acid. It is a colorless crystalline solid, soluble in water. When heated, it first melts and t..
