a litmus tells us if a substance is acidic or alkaline
an acid will turn red litmus paper blue and an alkali will turn blue litmus paper red.
if an unknown substance is tested with litmus and the colour did not change, then the substance is said to be neutral or it can be simply water.
note that water is needed for acids to show its acidic properties........
