Calcium hydroxide for lab grade
calcium hydroxide (50%)calcium hydroxide (50%)Neutralization Reactions: Calcium hydroxide is commonly used in titration experiments to neutralize acids. It reacts with acids to form water and a calcium salt.
Precipitation Reactions: It can be used to precipitate out impurities from solutions by forming insoluble calcium salts. This is often used in qualitative analysis to identify ions in solution.
Testing for Carbon Dioxide: When reacted with carbon dioxide, calcium hydroxide forms a white precipitate of calcium carbonate. This property is used to test for the presence of carbon dioxide in gas samples.
pH Adjustment: Calcium hydroxide can be used to adjust the pH of solutions. It is often employed to make solutions more basic, as it is a strong base.
Water Treatment: In laboratories, calcium hydroxide is sometimes used in water treatment processes to precipitate out impurities and improve water quality.
Desiccant: It has desiccant properties, meaning it can absorb moisture from the air. This makes it useful for drying gases in laboratory setups.
Laboratory Grade Reagent: Calcium hydroxide is commonly used as a reagent in various chemical reactions in the laboratory due to its availability and relatively low cost.
In Organic Synthesis: It finds applications in organic synthesis as a base catalyst for reactions such as the Cannizzaro reaction and the Knoevenagel condensation.
Soil Testing: In agricultural or environmental science laboratories, calcium hydroxide is used in soil testing to determine soil pH levels and nutrient availability.
These are some of the primary uses of calcium hydroxide in laboratory settings, but its versatility extends to various other applications depending on the specific experimental requirements.

Calcium hydroxide, commonly known as slaked lime or hydrated lime, is a white, crystalline substance with chemical formula Ca(OH)2. In lab-grade form, it is prized for its purity and consistent quality. Its key features include:
High Purity: Lab-grade calcium hydroxide is typically highly pure, minimizing impurities that could interfere with experimental results.
Alkalinity: It is strongly alkaline, making it useful in various laboratory applications including as a neutralizing agent or pH regulator.
Solubility: It is sparingly soluble in water, allowing for controlled release of hydroxide ions in aqueous solutions.
Reactivity: Calcium hydroxide exhibits reactivity with acids, forming calcium salts and water, which is essential in various chemical processes.
Desiccant Properties: It can absorb moisture from the air, making it useful as a desiccant in certain laboratory setups.
Precipitation Reactions: Its ability to precipitate certain ions from solution is valuable in qualitative analysis and separation techniques.
Safety: While generally considered safe, proper handling procedures should be followed due to its caustic nature.
Lab-grade calcium hydroxide is a versatile compound widely used in chemistry, biology, and environmental science laboratories for various purposes
