Question

Consider the following salt:

\[\ce{ZCO3}\]

What would be the change in colour in blue litmus if \[\ce{ZCO3}\] is added to it and Z is potassium?

Answer 1

Reaction with Blue Litmus:

• Since potassium carbonate is a basic salt, it will not affect blue litmus because blue litmus remains blue in a basic solution.
• There will be no change in the colour of the blue litmus paper.

There will be no change in colour in blue litmus when potassium carbonate \[\ce{K2CO3}\] is added to it.
