What is toothpaste in litmus paper is it acid or base? Toothpaste is enriched with fluoride to help prevent tooth decay. Fluoride ions are anions, meaning they have a negative charge. Take a look at where fluoride falls on the periodic table -- fluoride ions want to gain an electron to be more stable, thus they tend to form ions with a -1 charge.
Substances with negative charges are basic, while those with positive charges are acidic. An acid will turn litmus paper red and a base will turn litmus paper what color?

Red litmus paper is dipped into a solution to establish whether a substance is acidic or alkaline. In an acidic or neutral solution, red litmus paper remains red. In an alkaline solution, red litmus paper turns blue. When an alkaline compound dissolves in water, it produces hydroxide ions, which cause the solution to become alkaline. Red litmus paper can also be used to test the pH of a water-soluble gas by dampening the paper and exposing it to the gas.
While red and blue litmus papers can reveal whether a substance is acidic or alkaline, they cannot tell you the exact pH value of that substance. However, litmus papers are easy to handle and use. They give instantaneous readings and provide accurate results most of the time. Claire is a writer and editor with 18 years' experience.
