An indicator is a substance that changes color in response to acidity or alkalinity of a solution. By adding an indicator to a solution, you can observe the color change which helps distinguish between acids (low pH, turn red litmus paper blue) and bases (high pH, turn blue litmus paper red). This color change occurs at a specific pH range for each indicator, allowing you to determine whether the solution is acidic or basic.
What else can I help you with?
How do you distinguish hydrochloric acid and ethanoic acid by using an indicator?
Hydrochloric acid is a strong acid, so it will turn blue litmus paper red. Ethanoic acid is a weak acid, so it will not change blue litmus paper.
How is the endpoint of a titration between H3PO4 and NaOH determined?
The endpoint of a titration between H3PO4 (phosphoric acid) and NaOH (sodium hydroxide) is determined by using an indicator that changes color when the reaction is complete. This indicator helps to visually identify when the acid and base have reacted in the correct proportions, indicating the endpoint of the titration.
Can litmus be use to differentiating between sulphuric acid and ethanoic acid?
Yes, litmus paper can be used to differentiate between sulfuric acid and ethanoic acid. Sulfuric acid is a strong acid and will turn blue litmus paper red, while ethanoic acid (acetic acid) is a weak acid and will also turn blue litmus paper red, but the color change may not be as intense. A pH test strip or universal indicator may be more effective in distinguishing between these two acids due to their differing pH levels.
Why you use phenolphethalein indicator in titration?
Phenolphthalein is used as an indicator in titrations to visualize the endpoint of an acid-base titration. It changes color from colorless to pink in a basic solution, indicating the completion of the reaction between the acid and base. This change is easily detectable and helps to accurately determine the equivalence point of the titration.
A commonly used acid indicator is?
Litmus paper is a commonly used acid indicator. It changes color in response to the pH of a solution, turning red in acidic conditions and blue in basic conditions.
How does an indicator helps you distinguish between an acid and a base?
it has (red acid) and a (blue base)

What is the indicator of acid?
The indicator of acid is baking soda.
What is indicator neutralization?
Indicator neutralization is the process of adding a neutralizing agent to an acid-base indicator solution to adjust its pH level. This helps to ensure that the indicator functions properly and gives an accurate color change at the desired pH.
How can you distinguish between benzoic acid and benzene?
Benzoic acid will give brisk effervescence on reacting with sodium bicarbonate.

Why 2N sulphuric acid is used in oxalic acid estimation?
This titration is based on the neutralization reaction between oxalic acid and sulfuric acid; a pH indicator is used.
