Understanding the properties of hydrated salts is essential in chemistry.

Description

Properties of Hydrated Salts

Hydrated salts can lose their water of crystallisation upon heating, leading to changes in their physical properties. For instance, copper(II) sulfate changes color when it loses water.

  1. a

    Explain the significance of water of crystallisation in hydrated salts.

Description

Hydrated Crystals

Hydrated crystals contain water molecules that are part of their structure. For example, copper(II) sulfate pentahydrate (CuSO₄·5H₂O) and cobalt(II) chloride hexahydrate (CoCl₂·6H₂O) are two such compounds.

  1. a

    State the term used to describe the water molecules in hydrated crystals.

    Aim for approximately 1 distinct marking point.
