How to Make a Calcium Chloride Solution

Calcium chloride solutions are sprayed on apples to correct bitter pit problems, on cotton to prevent immediate crop loss, on non-crop areas as a dust suppressant and on roads as a de-icing agent. Calcium chloride solutions are also used in medical settings as a treatment for hypocalcemic tetany; however, you should never attempt any self-treatment with calcium chloride solution.
