just saying that I'm 12 and i know the answer!
an acid will turn red in litmus paper or a pinkcolour.
if it is a week acid it will turn yellow or green. :)
Red litmus paper is used to check for basicity. It turns blue when exposed to bases. Blue litmus paper is used to check for acidity. It turns red when exposed to acids.
It turns blue. Since chalk ( CaCo3) is a base and when pink litmus paper reacts with a base it turns blue
Well if you place blue litmus paper in saliva and it turns red, then the saliva is acidic. If you put red litmus in the saliva and it turns blue, then the saliva is alkaline. However, if the red litmus doesn't change colour and the blue litmus doesn't change colour, the saliva would be neutral.
Lemon juice contains citric acid so blue litmus paper dipped in lemon juice will turn red indicating that it is acidic.Blue litmus paper become red in acidic solutions (lemon juice contain citric acid).
Acid; Meaning it is ranked less than seven and at least zero on the pH scale.
A Blue litmus paper turns red in acid and stays blue in alkalin A red litmus paper turns blue in alkaline and stays red in acid
Red litmus paper stays red in the presence of an acid and turns blue in the presence of a base. Blue litmus paper stays blue in the presence of a base and turns red in the presence of an acid.
Litmus paper: red color in acidic solutions and blue color in basic solutions.Phenolphthalein: no color in acidic solutions.
A red litmus paper turns blue in the presence of a base/alkali, while a blue litmus paper turns red in the presence of an acid.
Blue litmus turns red in the presence of an acid. The opposite is correct in case of a base ie in presence of a base, red litmus turns blue in colour.
Ammonia turns red litmus paper blue, but does not have any effect on blue litmus parer, since it is a base.
Litmus Paper.
Litmus paper turns blue in the presence of a base like baking soda.
Litmus paper would turn red if apricot juice, which is acidic, was dropped on it. This is because litmus paper turns red in the presence of an acid.
Two examples of natural indicators of acids are red cabbage juice, which turns red in the presence of acids and green in the presence of bases, and litmus paper, which turns red in the presence of acids and blue in the presence of bases.
When litmus paper touches an acid, the paper changes to red. When it touches a base, the paper changes to blue. By comparing the color the litmus paper changed to by a chart, you could determine how strong or weak that acid or base is.
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.
