Uses of Potassium Chloride

Potassium chloride has several important uses:

1. Medical: It is used as a nutrient supplement and in medical treatments for conditions such as hypokalemia (low potassium levels).
2. Industrial: It is used in the production of fertilizers, in the manufacturing of glass, and in water softening processes.
3. Scientific: It is used in laboratory experiments and as a calibration standard in analytical chemistry.

Chemical Reactions

Potassium chloride can participate in various chemical reactions, including:

1. Formation of potassium hydroxide and hydrochloric acid when dissolved in water:
   KCl + H₂O → KOH + HCl
2. Precipitation reactions with other ions in solution, such as silver ions:
   AgNO₃ + KCl → AgCl ↓ + KNO₃
