Anhydrous calcium chloride and calcium chloride dihydrate are chemical products with certain distinctions. Below is an introduction for you.
1. Varying net contents.
Dihydrate calcium chloride contains less calcium chloride than anhydrous calcium chloride, with standards of 68%, 74%, and so on; the pure content of calcium chloride in anhydrous calcium chloride is higher than that in dihydrate calcium chloride, at approximately 90%, 94%, and so on.
2. Uniqueness.
Calcium chloride anhydrous can be used in some cases as a substitute for calcium chloride dihydrate, but calcium chloride dihydrate cannot replace calcium chloride anhydrous. Be sure to pay attention to this when using it. However, calcium chloride anhydrous typically contains a higher concentration and is easier to store, preventing caking.
