What else can I help you with?
Litmus paper and phenolphthalein are examples?
the actual answer is that litmus is an example of an indicator because... if for example you dip a blue litmus paper into lime juice (an acid) the litmus paper will turn red because it indicates that its an acid or......... if you dip a red litmus paper into a base it will turn blue because it indicates that it is a base..... so the answer is because it indicates if its an acid or basep.s. if the blue paper turned red---- indicates its a baseif the red paper turned blue ----- indicates its a acid or the other way around forgot... :/hopes this helped........ :)))))))))))
What are the most common liquid or paper indicators used in chemistry?

What different colors that acids turn in?
Acids can turn different colors in indicators like litmus paper. They turn red in litmus paper, yellow in phenolphthalein, and orange in methyl orange.
How can you test for acids and bases?
by using phenolphthalein,litmus paper (red and blue),cabbage,tea,and PH paper or PH meter
What is a color of limus paper and phenolphthlein in an acid?
Litmus paper: red color in acidic solutions and blue color in basic solutions.Phenolphthalein: no color in acidic solutions.
Substances that change color in an acid or base?
Litmus paper, phenolphthalein, and red cabbage juice are substances that change color in response to changes in acidity or basicity. Litmus paper turns red in acid and blue in base, phenolphthalein is colorless in acid and pink in base, and red cabbage juice turns red in acid and blue in base.
What is the reaction with litmus paper in carbon?
Carbon itself is not reactive with litmus paper as it is a non-metal element. Litmus paper is typically used to test for the presence of acids or bases. Carbon does not have acidic or basic properties, so it does not cause a visible change in litmus paper.
What colour does tomato juice turn phenolphthalein?

What is the chemical equation of the reaction of litmus paper to sodium chloride?
Litmus paper is a mixture of dyes that change color depending on the acidity or alkalinity of a solution. When exposed to sodium chloride, which is a neutral salt, litmus paper does not undergo a chemical reaction. It remains unchanged in the presence of sodium chloride.
Is turning litmus paper red from blue a chemical change?
Yes, turning litmus paper red from blue is a chemical change because the color change results from a chemical reaction between the litmus paper and the substance it comes into contact with, indicating a change in the chemical composition of the paper.
How can you test for hydroxide ion?
One way to test for hydroxide ions is by using red litmus paper. If the red litmus paper turns blue when dipped into a solution, it indicates the presence of hydroxide ions. Another method is to use a pH indicator, such as phenolphthalein, which changes color in the presence of hydroxide ions.
