Question

The pH of lemon juice and water are 2 and 7 respectively.
State the change in the colour of litmus when dipped in the above solutions.​

Answer 1

Answer:

$Litmus is extracted from lichens. It has a mauve (purple) colour in distilled water. When added to an acidic solution, it turns red and when added to a basic solution, it turns blue. So, it is used to test the acidic or basic nature of solutions.}$
