A Universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 1-14 to indicate the acidity or basicity of solutions. A universal indicator is typically composed of water, propan-1-ol, phenolphthalein sodium salt, sodium hydroxide, methyl red, bromothymol blue monosodium salt, and thymol blue monosodium salt.

∙ 12y agoIt is a substance used to determine the strengths of acids and alkali.
It changes colour according to the pH of the material it's in. It is so useful because the colour also tells you how strong the substance is. E.g. if you were to put a few drops of the indicator in water it would go green. A few drops of it in cleaning products and it would go a deep purple.
