Potassium Carbonate

Assertion : Potassium carbonate can be prepared by Solvay process like sodium carbonate using potassium chloride as starting material. Reason : Potassium carbonate is obtained as one of the porducts when potassium superoxide reacts with carbon dioxide.

(a) Potassium chlorate (KClO_(3)) on heating forms potassium chloride and oxygen. Write a balanced equation for this reaction and indicate the evolution of gas. (b) Rewrite the following information in the form of a balanced chemical equation Magnesium burns in carbon dioxide to from magnesium oxide and carbon.

Which of the following can be employed for the conversion of potassium manganate to potassium permanganate?

What happens when potassium iodide reacts with acidic solution of potassium dichromate ?

Potassium Dichromate

In a laboratory, a student added 2 mL of ethanol and 4 mL of sodium carbonate solution in a test tube and warmed the mixture for few minutes. He than slowly added few drops of potassium permanganate to this warm solution with constant stirring. He observed that the pink colour of potassium permanganate had disappeared. This is because _________
