Calcium Chloride

By Dominick Rhoden and Sunwoo Kim

What is Calcium Chloride and How Does It Work

Calcium chloride is a salt that is very good at "breaking the ice". CaCl2 has three particles, one calcium and two chlorine particles, that lower the melting point of the ice.

How well does it work (comparison to road/table salt)

CO$T

$5.60 for 500g of lab grade calcium chloride.

Environmental Effects

In Water (comparison to road/table salt)

CaCl2: Moderate - Excessive chloride loading; heavy metal contamination

NaCl: Moderate - Excessive chloride loading, metal contaminants; ferrocyanide additives

In Soil (comparison to road/table salt)

Cacl2: Low/Moderate - Improves soil structure; increases permeability; potential for metals mobilization

NaCl: Low/Moderate - Improves soil structure; increases permeability; potential for metals mobilization
