Indicators tells if something is acidic, alkaline or neutral. Indicators are substances that show different colours when they are in acidic or alkaline conditions. Litmus paper is a simple indicator that tells us whether something is acid or alkali. Litmus is red in acids, and blue in alkalis. It comes as red litmus paper and blue litmus paper. Red litmus paper changes colour from red to blue under alkaline conditions, but no change under acidic conditions. Blue litmus paper changes colour from blue to red under acidic conditions, but no change under alkaline conditions. The pH scale and universal indicator can give more information by telling us how acidic or alkaline something is. Universal indicator can show many different colour changes and so can be used to test the pH value of the solution. The pH scale runs from 0 to 14, with 0 being extremely acidic, 7 being neutral and 14 being extremely alkaline.
