indicators
An indicator is a thing that tells you whether an object is an acid or alkali
Red litmus
Red litmus paper turns Blue when dipped in an alkali and stay the same in an acid
Though it does not tell you the exact strength of the substance
Blue litmus
Blue litmus turns red in acid and stays the same in alkali
It does not tell you the exact PH
UI
UI stands for Universal indicator paper
Universal indicator paper is made of multiple dyes
It is a liquid
When mixed with an acid or alkali it uses the PH scale and shows you the exact colour and strength
UIP
UIP stand for universal indicator paper and has the same properties as UI
