To create solutions using solid calcium chloride products and water, it is recommended to use cool water and add the solid calcium chloride slowly while continuously mixing. If the solids are allowed to sit motionless while in contact with water, a hard cake may form, which will be slow to dissolve. It’s worth noting that dissolving solid calcium chloride will result in a temperature increase, the degree of which will vary based on the specific application. For instance, dissolving DOWFLAKE Xtra 83-87% Calcium Chloride Flakes may cause a temperature increase of 2.8°F per percentage increase in concentration. Therefore, when preparing a 30% solution, the temperature can be expected to increase approximately 84°F (30 x 2.8°F = 84°F). To achieve solutions of various concentrations, you can utilize the Making Solutions Calculator tool provided.
