Calcium Chloride

DESCRIPTION
Calcium Chloride Solution occurs as a clear to slightly turbid, colorless or slightly colored liquid at room temperature. It is normally available in a concentration range of about 35% to 45% of CaCl2.
Function: Sequestrant; firming agent.

REQUIREMENTS
Identification: When diluted to a concentration of about 1:10 (CaCl2 basis), a sample gives positive tests for Calcium and for Chloride.
Assay: Not less than 90.0% and not more than 110.0%, by weight, of the labeled amount of calcium chloride, expressed as CaCl2.
Alkalinity [as Ca(OH)2]: Not more than 0.3%.
Fluoride: Not more than 0.004%, calculated on the amount of CaCl2 as determined in the Assay.
Lead: Not more than 4 mg/kg, calculated on the amount of CaCl2 as determined in the Assay.
Magnesium and Alkali Salts: Not more than 5.0%, calculated on the amount of Calcium Chloride as determined in the Assay.
