[[File:LitmusPaper.png|right|300px|thumb|Two pieces of '''litmus paper''' dipped in an [[acid]] showing the red '''litmus''' stayed red but the blue '''litmus''' turned red.]]
'''Litmus paper''' is a piece of paper coloured with a [[dye]] that turns red in [[acid]] and blue in [[alkali]].
===About Litmus Paper===
: '''Litmus paper''' comes in two colours: Red and Blue.
: '''Litmus Paper''' is a very simple [[Indicator (Chemistry|indicator]] as it can only tell if something is [[acid]] or [[alkali]] but it cannot tell the exact [[pH]] of a [[solution]].
: '''Litmust Paper''' cannot be used on a [[base]] unless it is in [[solution]].
*When red '''litmus''' is placed in an [[acid]] it stays red.
*When red '''litmus''' is placed in an [[alkali]] it turns blue.
*When red '''litmus''' is placed in a [[neutral]] [[solution]] it stays red.
*When blue '''litmus''' is placed in an [[alkali]] it stays blue.
*When blue '''litmus''' is placed in an [[acid]] it turns red.
*When blue '''litmust''' is placed in a [[neutral]] [[solution]] it stays blue.
