See the chart below for comparisons. Generates heat as it dissolves â While most other deicers depend on their surroundings for heat, calcium chloride actually generates heat as it dissolves to form ice melting brine. A pound of calcium chloride can raise the temperature of a gallon of water by over 30Â°F (17Â°C).
