प्रश्न
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?
उत्तर
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.
