Sulfuric acid is added in iodometric titration to create an acidic environment, which increases the solubility of the iodine formed during the reaction. This ensures a more accurate and reliable titration by preventing the precipitation of iodine. Additionally, sulfuric acid helps to oxidize any interfering substances present in the sample, ensuring that only iodide ions are titrated.
What else can I help you with?
Why you do not use H2SO4 in iodometric titration?
Using H2SO4 in iodometric titration can lead to the formation of H2O2, which interferes with the reaction. It can also oxidize iodide ions prematurely, affecting the accuracy of the titration. Therefore, a different acid like HCl is typically used in iodometric 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 is the effect of adding the sulfuric acid before KI in iodometric titration?
Adding sulfuric acid before KI in an iodometric titration helps to acidify the solution and prevent the premature oxidation of iodide ions to iodine. This ensures that the iodide ions react with the analyte (substance being tested) instead of being oxidized by any oxidizing agents present in the solution. Acidifying the solution also helps to stabilize the iodine formed during titration.
What would happen when sulphuric acid is not added in spectrophotometric titration?
If sulfuric acid is not added in spectrophotometric titration, the acidic conditions required for the reaction between the analyte and the titrant may not be met. This could lead to inaccurate results or incomplete reaction, affecting the precision and reliability of the titration. Additionally, the absence of sulfuric acid may alter the chemistry of the system and prevent the formation of the colored complex that is usually measured in spectrophotometric titrations.
When dilute sulphuric acid is added to zinc granules the gas produced is?
When sulphuric acid is added to zinc granules , the gas produced is hydrogen gas. Zinc displaces hydrogen from sulphuric acid.

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.

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

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.
Does limestone fizz when sulphuric acid is added?
Yes
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.
Why did the solution turn to pink at the of the titration?
because the solution react with sulphuric acid. other than that, the end point is indicated.
What do you observe if dilute hydrochloric acid is added to the mixture of iron and sulphur?
ironchloride and sulphuric acid
