What is the difference between anhydrous calcium chloride and calcium chloride dihydrate?

The three major differences between anhydrous calcium chloride and calcium chloride dihydrate: 1. Form of existence: anhydrous calcium chloride and calcium chloride dihydrate are classified according to the form of calcium chloride molecules in the substance. Anhydrous calcium chloride contains no water at all, only a small amount of external water (about a few percentage points); each calcium chloride molecule in calcium chloride dihydrate exists in the form of two crystal waters, and the water content in the material is higher. High (this does not mean that its quality is not good, just a state of existence of matter). 2. Appearance: anhydrous calcium chloride is generally spherical with a diameter of 2-6 mm. Calcium chloride dihydrate is generally in the form of flakes with a thickness of 1-2 mm. The color is as high as white, and the purity is low, and the whiteness is lower. 3. Net content: The net content of calcium chloride in anhydrous calcium chloride is 90% or more, and the net content of calcium chloride in calcium chloride dihydrate is about 70%.
