About This Product
Left exposed, fused calcium chloride quickly takes up water from the air, and it is used to demonstrate hygroscopic and deliquescent behaviour. For solutions, it is added slowly to water while stirring, never water onto a large pile of solid, and the solution is left to cool before transfer. The container is kept tightly closed and the solid handled with a clean, dry spatula, goggles and gloves.
Frequently Asked Questions
Q1. Why does calcium chloride solution get warm?
Dissolving calcium chloride in water releases heat, so it is added slowly with stirring and the solution is allowed to cool.
