Expert Answer:

With the help of indicators, we can test acids and bases.
 
  • Methyl orange indicator gives a red colour in an acidic solution and gives a yellow colour in a basic solution

  • Phenolphthalein is colourless in an acidic solution and gives a pink colour in a basic solution.

  • An acid turns the blue litmus to red and a base turns the red litmus to blue.
