litmus paper is a paper stained with litmus which is used to indicate the acidity or alkalinity of a substance. Blue litmus paper turns red under acid conditions, and red litmus paper turns blue under alkaline conditions.
the drink which is basic in nature will turn red litmus paper blue
the drink which is acidic in nature will turn blue litmus paper into red
when the litmus paper will be dipped into neutral drink the litmus paper will not change it's colour
