Question

1. WHAT IS THE COLOUR OF LITMUS SOLUTION IN A NEUTRAL SOLUTION?
2. WHY DOES BLUE LITMUS SOLUTION CHANGE ITS COLOUR IN AN ACIDIC SOLUTION BUT NOT IN A BASIC ONE?
3. WHY DOES RED LITMUS SOLUTION CHANGE ITS COLOUR IN A BASIC SOLUTION BUT NOT IN AN ACIDIC ONE?

Answer 1

1) There will be no change in the colour of litmus solution.

2) This is because only acids turn blue litmus to red while bases have no effect on blue litmus solution.

3) Bases have a tendency to change the red litmus to blue while acids turn blue litmus to red. So, acids have no effect on red litmus solution.
