In the titration of sulfuric acid with sodium hydroxide (NaOH), a pH indicator suitable for a strong acid-strong base titration, such as phenolphthalein, can be used. Phenolphthalein changes color at around pH 8.2-10, which is suitable for detecting the endpoint of the neutralization reaction between sulfuric acid and sodium hydroxide.
What else can I help you with?
What colour would the red petal indicator be in a solution of sulphuric acid?
The red petal indicator would likely turn blue in a solution of sulphuric acid because sulphuric acid is a strong acid that would cause the indicator to change color.
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 do you find concentration of an acid from a titration?
To find the concentration of an acid from a titration, you would use the stoichiometry of the reaction to determine the moles of acid that reacted with the known concentration of base. Then, you would use this information to calculate the concentration of the acid by dividing the moles of acid by the volume of the acid used in the titration.
Why is 4 normal sulphuric acid added to the titration flask?
4-nitroaniline, an organic compound, is being titrated with sulphuric acid in the mixture to help solubilize the compound. This aids in the reaction and allows for accurate titration results to be obtained.
What colour should sulfuric acid be after universal indicator is added?
Sulphuric Acid is colourless. When universal indicator (UI) is added, sulphuric acid remains colourless. The universal indicator turns 'RED'. Howver, because the UI is in solution with the sulphuric acid, the solution appears to be red.
What colour would the red petal indicator be in a solution of sulphuric acid?
The red petal indicator would likely turn blue in a solution of sulphuric acid because sulphuric acid is a strong acid that would cause the indicator to change color.
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.
What is the concentration of sulphuric acid?
There are many different concentrations of "concentrated sulphuric acid". It is possible to deduce the concentration of the sulphuric acid by titration.
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.
Why do you have to heat up the solution of oxalic acid after adding sulphuric acid for the titration with permanganate?
To act as a catalyst

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.
Is phenolpthalen an indicator?
Yes - it's used in acid-base titration.
Which indicator is used for the titration of weak acid and strong base?
Phenolphthalein is commonly used as the indicator for the titration of a weak acid and a strong base. It changes color from colorless to pink at the equivalence point of the titration when the weak acid is completely neutralized by the strong base.
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.
