They turn it either red or blue. Acids turn blue litmus paper red and bases turn red litmus paper blue.
For a common litmus (Acid only or Base only), would stay the same shade.
Litmus is used to test materials for their acidity. Blue litmus paper turns red when exposed to acid, so it would turn red when exposed to vinegar, which is acidic.
An acid turns blue litmus paper red
Litmus is a natural dye indicator extracted from lichens.They react with acid (blue litmus turns red)& bases(red litmus turns blue) .Paper made with litmus dye indicators are called litmus paper and used in chemical laboratories.
When blue litmus paper touches an acid it becomes red. This is the type of litmus paper that detects acids. When red litmus paper touches an acid, it will remain red. This is used to test a base.

Sour milk is acidic. Red litmus paper should not change.The sour part of sour milk is lactic acid. As litmus paper turns red when exposed to acidic compounds, litmus paper that is already red should not react when exposed to lactic acid.
Acid will turn litmus paper red.
Litmus is used to test materials for their acidity. Blue litmus paper turns red when exposed to acid, so it would turn red when exposed to vinegar, which is acidic.
An acid turns the blue litmus paper red.
