Question

3) Formation of compound- Potassium fluoride. write short note
​

Answer 1

Answer:

In one method for making potassium fluoride, potassium carbonate (K2CO3) is dissolved in hydrofluoric acid, resulting in the formation of potassium bifluoride (KHF2): K2CO3 + 2H2F2 → 2KHF2 + CO2 + H2O. The potassium bifluoride is then heated to form potassium fluoride and hydrogen fluoride: KHF2 → KF + HF.

FORMULA: KF

ELEMENTS: Potassium, fluorine
