hello dear frii!!
As we know there are acids and bases which can be checked or identified through various substances like methyl orange and phenolphathelin etc. universal indicator is also kind of tool through which we can identify the substance whether it is basic or acidic in nature a mixture of dyes that changes colour gradually over a range of pH and is used (especially as indicator paper) in testing for acids and alkalis.
