What is the most appropriate indicator for the strong acid/strong base titration?
The most appropriate indicator for a strong acid/strong base titration is phenolphthalein.
How you can determine urea concentration by classical titration?
use the non aqueous titration dissolved urea in glacial acetic acid, and titrate with standard 0.1 mol/L trifluoromethanesulfonic acid in acetic acid using isobutyl vinyl ether as a thermometric endpoint indicator
What is the process to calculate the percentage of acetic acid in vinegar?
To calculate the percentage of acetic acid in vinegar, you can use a simple titration method. First, you need to titrate a known volume of vinegar with a standardized solution of sodium hydroxide (NaOH) using phenolphthalein as an indicator. The volume of NaOH required to neutralize the acetic acid in the vinegar can be used to calculate the concentration of acetic acid. Finally, you can convert the concentration to a percentage by considering the molar mass of acetic acid.
Why is acetic acid needed for the titration of vitamin C?
Acetic acid is needed in the titration of vitamin C to create an acidic environment that stabilizes the ascorbic acid molecule, preventing oxidation. This ensures accurate results during the titration process by maintaining the stability of the vitamin C solution.
What is the indicator used in sulphonic acid titration?
Titration with strong base requires eg. methyl red, changing to yellow at 6.2, but it endpoint may come too early when the sulfonic acid is weaker than acetic acid: OK if pKa < 4.5 .So it's safer to use phenolphaleine (purple at pH=8.5) for acids with pKa < 8
What is the most appropriate indicator for the strong acid/strong base titration?
The most appropriate indicator for a strong acid/strong base titration is phenolphthalein.
Can the acidity due to acetic acid be found out by the titration procedure?
N cannot be found by the titration procedure because the acetic acid is very weak acid and cannot be appear completely during the tit ration procedure

What colour should Acetic acid be in universal indicator?
Acetic acid, a weak acid, is typically a colorless liquid in universal indicator. When dissolved in water, acetic acid will appear yellow, indicating it is acidic with a pH around 3-4.
What indicator can you choose for the titration of oxalic acid with sodium hydroxide?
Phenolphthalein is a suitable indicator for the titration of oxalic acid with sodium hydroxide. It changes color from colorless to pink at the endpoint of the titration when the acid has been completely neutralized.
What are the examples of acid base titration?
Determination of the concentration of a base by titration with acids or determination of the concentration of an acid by titration with bases. (http://en.wikipedia.org/wiki/Acid-base_titration)
What colour is produced when universal indicator is added to acetic acid?
When universal indicator is added to acetic acid, it typically turns a shade of red, indicating that the solution is acidic. Acetic acid is a weak acid, so the color change may not be as intense as with stronger acids.
Is phenolpthalen an indicator?
Yes - it's used in acid-base titration.
