Calcium Chloride Extra Pure is a highly pure, hygroscopic compound widely used in laboratory applications as a desiccant, electrolyte source, and reagent in analytical chemistry. It is effective in moisture control, gas drying, and as a coagulant in biological and biochemical processes. Its strong affinity for water also makes it valuable in experiments involving freezing point depression, exothermic dissolution, and ionic reactions. The extra pure grade ensures minimal impurities, which is critical for accuracy in quantitative analysis, buffer preparation, and synthesis. It should be stored in well-sealed containers in a dry environment to prevent clumping and preserve its chemical performance.
Calcium Chloride Extra Pure
Primary Uses
- Drying Agent / Desiccant
- Widely used to dry gases and organic solvents in drying tubes or desiccators due to its strong hygroscopic nature.
- Often chosen for drying non-polar solvents (e.g. ethers, hydrocarbons).
- Source of Calcium Ions in Reactions
- Supplies Ca²⁺ ions for precipitation reactions, analytical tests, or ionic exchange studies.
- Common in flame tests, where calcium imparts an orange-red flame.
- Electrolyte in Electrochemical Studies
- Acts as an ionic conductor in electrolysis and conductivity experiments, especially when calcium ions are involved.
- Osmotic and Cell Treatment Agent
- Occasionally used in molecular biology for preparing competent cells in bacterial transformation processes.
Secondary Uses
- Thermochemical Demonstrations
- Used in exothermic dissolution experiments to demonstrate enthalpy of solution and heat transfer.
- Colligative Properties Experiments
- Ideal for studying freezing point depression and boiling point elevation in solution chemistry.
- Simulation of Hard Water
- Helps recreate hard water conditions in lab studies related to water softening or soap efficiency testing.
- Standard for Moisture Absorption Tests
- Applied as a benchmark for evaluating hygroscopic properties in comparative material science studies.

Ammonium Carbonate Extra Pure is a high-quality, white crystalline solid widely used across various scientific, industrial, and food-related applications. Manufactured to stringent purity standards, this compound is ideal for laboratories and processes that demand high-grade reagents. With its characteristic ammonia-like odor and ability to decompose upon heating, ammonium carbonate plays a versatile role in both chemical reactions and physical processes.
In aqueous solution, ammonium carbonate breaks down into ammonium bicarbonate and ammonium carbamate, further releasing ammonia (NH₃) and carbon dioxide (CO₂) upon heating. This property makes it especially useful in applications that require controlled gas release or temporary pH modification.
