Description

Chemical Tests for Water

Anhydrous cobalt(II) chloride and anhydrous copper(II) sulfate are commonly used to detect the presence of water. Cobalt(II) chloride changes from blue to pink, while copper(II) sulfate changes from white to blue when they come into contact with water.

  1. a

    State the color change of anhydrous cobalt(II) chloride when it detects water.

    Aim for approximately 1 distinct marking point.
