Question : When the litmus solution is neither acidic nor basic, its colour is_____.
Option 1: green
Option 2: red
Option 3: purple
Option 4: blue
Correct Answer: purple
Solution : The correct option is purple.
When the litmus solution is neither acidic nor basic, its colour is purple. Litmus is a natural dye that turns red in acidic conditions and blue in basic solutions. In a neutral solution, it retains its original purple hue. Litmus solution is purple in its neutral state because litmus is a natural dye extracted from lichens.
