massive, the round shape, irregular granular, powder. Non-toxic,
odourless, taste slightly bitter. Moisture absorption sex is
extremely strong, exposed to the air ChaoXie extremely easily.
Soluble in water, and give off a lot of heat, its water solution
are acidic. Soluble in alcohol, acetone, acetic acid. And ammonia
or ethanol role, generating CaCl2 respectively · eight NH3 and
CaCl2 · 4 C2H5OH complex. Low temperature and precipitation of
crystallization solution for six water content, gradually heating
to *0 ℃, dissolved in their own crystallization water, continue
to heat water loss gradually, to **0 ℃ to two things when water,
then heated to **0 ℃ is a white form of porous calcium chloride
