Red litmus paper dipped in vinegar will turn red, indicating that vinegar is acidic. This change in color is due to the red litmus paper reacting with the acidity of the vinegar, causing it to remain red. Litmus paper is commonly used to test the acidity or basicity of a solution by observing the color change it undergoes.
The answer isn't so simple. There are various kinds of pH paper. However, I presume you are referring to litmus paper which is the widest distributed form. Acetic acid has no effeect on red litmus paper but turns blue litmus red
