Potassium hydroxide (chemical formula: KOH) is a white solid with strong corrosiveness and alkalinity. The following is a detailed introduction to the properties, uses, preparation methods, and safety information of potassium hydroxide: Potassium Hydroxide (CAS: 1310-58-3) Chemical Formula: KOH Properties: - Potassium hydroxide is a strong base that dissolves completely in water, producing a potassium hydroxide solution. This solution is alkaline and can neutralize acidic substances. - Potassium hydroxide is corrosive and can react with many organic and inorganic substances. - It can absorb moisture and rapidly absorb carbon dioxide to form potassium carbonate. Uses: - Potassium hydroxide is widely used in chemical laboratories as a common chemical reagent. - It is used in the production of everyday items such as soaps, detergents, and lubricants. - Potassium hydroxide is also an important raw material in industries such as electroplating, aluminum anodizing, cellulose production, and paint formulation. Preparation: - A common method for preparing potassium hydroxide is by reacting potassium metal with water. The reaction formula is: 2K + 2H₂O → 2KOH + H₂. - Another method is to obtain potassium hydroxide by reacting potassium chloride with hydrated sulfuric acid, followed by electrolytic hydrolysis. Safety Information: - Potassium hydroxide is a strong corrosive agent; contact with skin, eyes, or respiratory tract can cause irritation and burns. When handling it, wear protective gloves, goggles, and protective clothing. - Potassium hydroxide should be stored in a dry, well-ventilated place, away from sources of ignition and organic matter. - Waste should be disposed of properly in accordance with local regulations and rules to avoid environmental pollution.
