Calcium Chloride Dihydrate Extra Pure

Primary Uses

Drying Agent / Desiccant
- Used to absorb moisture from gases or organic solvents in drying tubes, desiccators, and sample preservation.
- Preferred in cases where mild hygroscopic action is required without strong exothermic reactions.
Source of Calcium Ions in Reactions
- Provides Ca²⁺ ions in qualitative and quantitative chemical analysis, often in double displacement reactions, flame tests, or ionic precipitation studies.
Electrolyte in Laboratory-Scale Experiments
- Utilized in electrochemical cells or conductivity studies where calcium ions are needed.
Osmotic Agent in Molecular Biology
- Sometimes used in bacterial transformation protocols to increase cell membrane permeability in CaCl₂-competent cell preparation.

Secondary Uses

Freezing Point Depression Studies
- Used in colligative property experiments to demonstrate depression of freezing point and understand solute effects in solutions.
Heat Generation Demonstrations
- Dissolution in water is exothermic, useful for energy change (enthalpy) experiments or to demonstrate solvation heat release.
Precipitation Reactions in Teaching Labs
- Reacted with sodium carbonate or oxalate to form precipitates (e.g., CaCO₃ or CaC₂O₄), common in qualitative analysis training.
