it is litmus not lithmus . it is a natural indicator . it is a strip of paper either red or blue in colour . it is used whether a solution is acidic or basic in nature. a basic solution turns red litmus to blue and an acidic solution turns blue litmus into red
The function of litmus paper is to determine if a solution is acidic, or basic.
An acidic solution will turn blue limus paper red, and a basic silution will turn red litmus paper blue.
in red lithmus paper is turns blue on blue lithmus paper it does nothin.
Try one drop on lithmus paper: basic is blue, acid is red
Al2O3 is very INsoluble in water, so it doesn't change lithmus paper color.
base
One could use the color change of lithmus paper or other acid/base pH-indicator commercially available.
in red lithmus paper is turns blue on blue lithmus paper it does nothin.
lithmus paper
It is a indicator. It indicates colors according to acidity.
if you are working with a strong acid the lithmus paper will turn red.
Red color in acidic solutions and blue color in basic solutions.

Litmus is a mixture, not a single compound.
base

Surely there is a distinct difference in color:the second is the color when immersed in acidic solutions (red), the first is the 'basic solution's color (blue), but in both cases it is still 'lithmus paper'.
