How much phenolphthalein indicator should be used?
Typically, 1-2 drops of phenolphthalein indicator are sufficient to use in an acid-base titration experiment. It is important not to use too much indicator, as it can affect the accuracy of the titration results.
Why is it that 2 or 3 drops of the indicator is added during titration of acid and base?
Adding a few drops of indicator helps to visually identify the endpoint of the titration, which is the point at which the reaction is complete. The indicator changes color at a specific pH, indicating that the acid and base have been completely neutralized. This helps the titrator know when to stop adding the titrant.
What tools are used during and acid-base titration experiment?
During an acid-base titration experiment, tools commonly used include a burette to deliver the titrant, a pipette to measure the volume of the analyte solution, an indicator to detect the endpoint, and a pH meter to precisely determine the endpoint. Additionally, a flask or beaker, a stirring rod, and a clamp stand may also be used in the experiment.
What tools are used during and acid base titration experiment?
Burette Methyl orange Phenolphthalein Pipette
What is the best acid base indicator?
One commonly used acid-base indicator is phenolphthalein, which is colorless in acidic solutions and pink in basic solutions. Another popular indicator is litmus, which turns red in acidic solutions and blue in basic solutions. The choice of the best indicator depends on the specific experiment and the pH range being tested.

How can you find out how acidic somethig is?
use the pH scale by adding 1 or 2 drops of universal indicator in an acid or an alkali
What is the indicator of acid?
The indicator of acid is baking soda.

Could you add drops of a solution that was indicated acid into a solution that was indicated base until they became neutral?
Yes, you can add drops of an acid solution into a basic solution until they reach neutral pH. This process involves titration, where you gradually add the acid solution until the pH reaches around 7, which is neutral. It's important to use an indicator or a pH meter to monitor the pH levels during this process.
How can you tell if the burrette contains the acid or base?
You can determine if a burette contains acid or base by using a pH indicator. Simply add a few drops of the indicator to the solution in the burette and observe the color change. Red or pink indicates an acid, while blue or green indicates a base.
Show by experiment that how plants are useful indicator species for acid rain pollution?
Lichens are a good indicator species for acid rain. Lichens absorb water and nutrients from the air. They absorb the nutrients that they need from the water. Rainwater contains enough sulphur dioxide to make them stop growing.
What colour is citric acid in universal indicator?
Citric acid is generally colorless in universal indicator. It is a weak acid, so it does not exhibit a strong color change in the indicator solution.
Why is phenolpthalein used as the indicator for the assay of tartaric acid?
Phenolphthalein is used as an indicator during the titration of tartaric acid because the pH at which phenolphthalein changes color (around pH 8.2-10) is close to the equivalence point of the titration of tartaric acid with a strong base like NaOH. This makes it a suitable indicator for detecting the endpoint of the titration when the acid has been completely neutralized by the base.
