1. Food & Healthcare Ingredients 

• Leavening Agent in Baking: Used in baked goods as a leavening agent, especially where sodium content needs to be reduced. It releases CO₂ when heated or in acidic environments, helping dough rise.
• Low-Sodium Salt Substitute: Used in dietary salt formulations to provide potassium without sodium, helping reduce blood pressure and promote heart health.
• Acidity Regulator: Acts as a pH buffer in processed foods and beverages, especially in carbonated drinks, cocoa powder, and wine production.

2. Agrochemicals

• Fungicide for Crops: Registered as a biorational fungicide, potassium bicarbonate controls powdery mildew, blight, and molds on fruits, vegetables, and ornamental plants by disrupting fungal cell walls.
• Foliar Nutrient Spray: Provides potassium nutrition to crops through foliar applications, helping with fruit development, drought resistance, and stress tolerance.
• Soil pH Adjustment: Used to neutralize slightly acidic soils, improving nutrient availability and promoting balanced plant growth.

3. Pharmaceuticals 

• Antacid in OTC Formulations: Used in effervescent antacid tablets to relieve heartburn and indigestion. It reacts with gastric acid to form potassium chloride, water, and CO₂.
• Electrolyte Replenishment: Acts as a source of potassium in oral rehydration salts (ORS) and electrolyte blends, important for restoring electrolyte balance.
• Alkalizing Agent: Used in certain urinary alkalizers to manage conditions like uric acid stones and metabolic acidosis.

4. Performance Chemicals

• Intermediate for Potassium Compounds: Acts as a precursor or buffering agent in producing other potassium salts like potassium carbonate and potassium acetate.
• CO₂ Source in Controlled Reactions: Releases carbon dioxide under heat or acid exposure, which is used in controlled chemical syntheses.
