Frequently Asked Questions About Calcium Chloride Dihydrate

What is Calcium Chloride Dihydrate used for in laboratories?

Calcium Chloride Dihydrate is used in aqueous solution preparation, precipitation experiments, qualitative inorganic analysis, and investigations of ionic properties. It provides calcium and chloride ions for suitable laboratory procedures. Its use in analytical methods depends on the required concentration, reagent grade, and method-specific specifications.

What is the chemical formula and molecular weight of Calcium Chloride Dihydrate?

The molecular formula is CaCl₂·2H₂O, and its formula mass is approximately 147.02 g/mol. The formula includes two water molecules of crystallization. This differs from anhydrous calcium chloride, CaCl₂, which has a lower formula mass and must not be substituted without adjusting relevant calculations.

What is the CAS number of Calcium Chloride Dihydrate?

The CAS Registry Number for Calcium Chloride Dihydrate is 10035-04-8. This identifier distinguishes the dihydrate from anhydrous calcium chloride, which has a different CAS number. Confirming the CAS number and hydrate form helps laboratories select the correct chemical for experiments and solution preparation.

Is Calcium Chloride Dihydrate suitable for educational and research laboratories?

Calcium Chloride Dihydrate can be used in supervised school practicals, college experiments, university teaching laboratories, and research investigations when the application is appropriate. The required grade, concentration, and specifications should be checked before use. Students should follow laboratory instructions and applicable safety procedures.

How should Calcium Chloride Dihydrate be stored and handled safely?

Store the reagent in a tightly closed, compatible container in a cool, dry, well-ventilated place. Avoid unnecessary exposure to moisture because calcium chloride is hygroscopic. Wear suitable protective gloves and safety glasses, minimize dust formation, and avoid eye contact. Consult the current Safety Data Sheet for detailed precautions.

Storage Conditions for Calcium Chloride Dihydrate

Store Calcium Chloride Dihydrate in a tightly closed, moisture-resistant container in a cool, dry, well-ventilated area at the recommended room-temperature conditions. Protect the material from excessive moisture and avoid unnecessary exposure to humid air. Keep containers properly labelled and segregate the reagent from incompatible materials in accordance with the applicable Safety Data Sheet.

Precautions for Handling Calcium Chloride Dihydrate

Review the current Safety Data Sheet before handling Calcium Chloride Dihydrate. Wear suitable safety glasses, protective gloves, and a laboratory coat.
