Indicators can differentiate between acids and bases based on their chemical properties. Indicators change color depending on the pH of the solution they are added to. For example, acids will turn indicators like litmus paper red, while bases turn them blue. This color change occurs because indicators respond to changes in hydrogen ion (H+) concentration in the solution.

Why is it that the presence of indicator does not affect reaction between acid and base?
Indicators do not interfere with the reaction between an acid and a base because they are typically weak acids or bases themselves. They only change color depending on the pH of the solution but do not participate in the acid-base reaction. This allows the reaction between the acid and base to proceed as normal.
Indicators used in acid base titration?
Some common indicators used in acid-base titrations are phenolphthalein (which turns pink in basic solutions), methyl orange (which changes from red to yellow in acidic solutions), and bromothymol blue (which shifts from yellow to blue in basic solutions). These indicators help visualize the endpoint of the titration by changing color at the equivalence point of the reaction.
What is the difference between a redox indicator and an acid-base indicator?
A redox indicator changes color based on changes in oxidation states in a chemical reaction, where electrons are transferred. An acid-base indicator changes color based on changes in hydrogen ion concentration (pH) in a chemical reaction, without involving electron transfer.
What substance is used as an acid-base indicator?
Common substances used as acid-base indicators include litmus, phenolphthalein, and bromothymol blue. These indicators change color in response to changes in the acidity or alkalinity of a solution, making it easier to determine the pH level.
Why do you use litmus paper to tell the difference between acid and base?
Litmus paper changes color in the presence of an acid or a base due to its pH-sensitive properties. In an acid, litmus paper turns red, while in a base, it turns blue. This color change helps to quickly distinguish between the two types of substances.
What are acid-base indicators?
Acid-base indicators, are chemicals that change color in response to acidic or basic conditions.
What are the household use of acid-base indicator?
common household indicators of acid base
What is acid-base indicators?
These indicators change the color depending on the pH of the solution.
What are acid base indicators?
These indicators are substances which change their color depending upon acidity/basicity of the solution.
Why is it that the presence of indicator does not affect reaction between acid and base?
Indicators do not interfere with the reaction between an acid and a base because they are typically weak acids or bases themselves. They only change color depending on the pH of the solution but do not participate in the acid-base reaction. This allows the reaction between the acid and base to proceed as normal.
what acid-base change color when in contact with an acid or a base?
pH indicators change the color in contact with acids or bases.
What is the Chemical name for an acid base indicator?
there are many types of acid base indicators - see chart at http://chemistry.about.com/library/weekly/aa112201a.htm Common indicators: Methyl orange - acid=red, base=orange Bromcresol green - acid=yellow, base=blue Bromphenol blue - acid=yellow, base=blue Phenolphthalein - acid=colorless, base=red it is also easy to use litmus paper - acid=red, base=blue
Is flammability a example of chemical property?
Yes, because it shows you the difference between an acid or a base. An of course its both an acid and a base?
What is status indicators?
indicators are a slip of paper that detects wether a substance is an acid or a base, but having the paper change colors
What are some indicators?
Indicators are chemicals that change color in the presence of an acid or a base. The most commonly used indicator is phenophthalein.
Is a indicator an acid or base?
Yes, indicators are one or the other of those things.
Is an indicator base or acid?
Yes, indicators are one or the other of those things.
