Calcium Chloride Hexahydrate (CaCl₂·6H₂O) – LR Grade, 500g

Calcium Chloride 6H₂O, also known as calcium chloride hexahydrate, is a high quality Laboratory Reagent (LR) grade salt supplied in a 500g container for educational laboratory use. This hydrated inorganic compound is widely used in school science due to its strong water solubility and clearly observable thermal and chemical properties.

The compound has a CAS Number of 7774‑34‑7 and no UN number assigned (UN: NR). It is supplied as a white, crystalline solid containing six molecules of water of crystallisation. When dissolved in water it produces noticeable heat, making it especially useful for demonstrations involving exothermic reactions.

Clearly labelled and easy to store, this reagent is suitable for routine use in school laboratories when handled in accordance with standard laboratory safety procedures.
