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.
What will happen to the litmus paper if its blue and placed in toothpaste
it is an alkali not acid
Red litmus paper will turn blue in the presence of a base. Toothpaste is a base, so the litmus paper would turn blue.
It turns it
A base/alkali substance will turn litmus paper blue.
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.
It depends. Litmus paper is used to test pH levels. Blue litmus paper turns red in the presence of acids, and red litmus paper turns blue in the presence of alkalines. Litmus paper is purple in neutral conditions.
1. It tastes bitter.2. Feels slippery.3. Turns red litmus paper blue.a base is a substance that tastes bitter, feels slippery, and turns red litmus paper blue.

pH paper and litmus paper
It depends. Litmus paper is used to test pH levels. Blue litmus paper turns red in the presence of acids, and red litmus paper turns blue in the presence of alkalines. Litmus paper is purple in neutral conditions.
No an acid will only change the litmus paper red regardless of of the substance color.
Litmus paper is used to indicate whether a substance is acidic or basic. Blue litmus paper turns red in the presence of an acid, while red litmus paper turns blue in the presence of a base.
