Sulphuric acid helps in maintaining pH around 3-4 which further helps in liberation of iodine upon adding KI solution.

What is iodometric titration?
In this titration iodine is liberated ....Added:... from (excess of) iodide by an oxidant. The Iodine is then titrated with thio (di-sodium thio-sulfate) and starch as indicator added just before the expected equivalence point.
What is the trial titration?
A trial titration is carried out before the actual titrations and is not recorded. It is carried out by adding increments of several milliliters from the reactant in burette. It helps to give a rough estimation to the end point.
Why is indicator added to a pipette solution before titration?
I'm not sure what you really mean. There wouldn't be any point adding it afterwards! It's there to reveal the end point of your titration. You could add it when you thought you were near the end point, but it's easier to put it in before you start.
Why is the vinegar diluted before titration?
1. The advantage in diluting the solution before titration is that it allows for greater accuracy in the titration; this is because the color change in the solution is easier to observe if it is a dilute solution.
Why the solution is boiled before titration?
because in those cases, the endpoint will not be correct if the titration is carried out at low temperature

What is The process of adding a known amount of solution of known concentration to determine the concentration of another solution is called?
titration is the best method to determine the unknown concentration of the unknown. if ur known is a solid then you would have to used distilled water to ensure it is submerged before you titrate.

Where is the buffer region in a titration curve for the titration of a weak acid with a strong base?
It is the nearly horizontal region before the equivalence point.
Why oxalic acid is acidified before titration?
for medium produce
Why do you need to remove the funnel before carrying out the titration?
chicken
Is there such a thing as sulfuric acid poisoning?
No, you cannot be poisoned by sulfuric acid. You will die from internal hemorrhaging resulting from the corrosive effect of concentrated sulfuric acid before you are poisoned by it.
What is the purpose of adding sulfuric acid to iron samples before titration?
Depends on the method used. In general, it helps to dissolve all the sample. But in case of using manganometry in the determination, then the acid is needed to ensure low pH, because the reaction Fe2+ + MnO4- = Fe3+ + Mn2+ proceeds only in high pH. If the pH was neutral or basic, solid MnO2 would be created, which is not favorable (we need to know prpreciselyow many mno4- oxidates one fe2+).
What is the pH of the solution before the titration?
This depends on what kind of solution you are about to titrate.
