Question 11

When chloride ions are added to a pink solution containing cobalt ions, the mixture turns blue.

This is a reversible reaction.

pink solution+chloride ions⇌blue solution+water \text{pink solution} + \text{chloride ions} \rightleftharpoons \text{blue solution} + \text{water} pink solution+chloride ions⇌blue solution+water

What effect does the removal of chloride ions have on the colour of the blue mixture?

A

turns pink

B

turns darker blue

C

turns colourless

D

does not change colour
