Liquid calcium chloride has the characteristics of alkaline, conductive, low freezing point and high boiling point:
1. Alkaline: The hydrolysis of calcium ions is alkaline, and the hydrogen chloride is easily volatilized after hydrolysis of chloride ions.
2. Conductive: There are ions in the solution that can move freely.
3, freezing point: liquid calcium chloride freezing point is lower than water.
4. Boiling point: The boiling point of liquid calcium chloride is higher than that of water.
5. Evaporation crystallization: Liquid calcium chloride is evaporated and crystallized in an atmosphere filled with hydrogen chloride.
