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.
What is the pH of the solution before the titration?
This depends on what kind of solution you are about to titrate.
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
Why do we heat KSCN Fe solution befor titration with EDTA?
We usually heat KSCN Fe solution before titration with EDTA so as to produce crystalline crust forms.
Why is it necessary to standardize the NaOH solution before titration?
It allows the concentration of the NaOH to be known.

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.
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 do you have to warm the oxalate solution before performing titration?
because if the temperature is too low the interaction between the oxylate and potassium permanganate will move too slow?? why IDK
Why KmnO4 is used as self indicator?
As we all know that the potassium permanganate (KMnO4) is the dark purple color solution ...and in titration it become colorless ....so when the titration is completed ...and the other single drop of KMnO4 solution produce pinkish colour in a beaker ...which indicate that the reaction was completed just a single drop before .. we use indicator in a a reaction in order to indicate ...but we dont used indicator in titration with KMnO4 because it also indicate us by changing its color ...colorless to pink
Why was an acid added to the iron II ammonium solution before titration?
To create an acidic medium or in another word made iron (II) ammonium solution more acidic as kmno4 acts as a strong reducing agent only in acid medium.
What are different types of EDTA titration?
1. Direct Titration In direct titration, you simply add an indicator to the solution of the metal ion and titrate with EDTA. Before starting the titration,it is needed to check that the pH of the solution to obtain a good formation constant value and on the other hand indicator colour change as well. 2.Indiract titration EDTA can be used as titrant for anions. Anions can be precipitated with suitable metal ion. Filter and wash the ppt with proper solution. Then boil in excess EDTA to complex metal ion(ppt). Back titrate to determine how much metal ion you had. 3.Back Titration In a back titration an excess of EDTA is added to the metal ion solution, and the excess EDTA is titrated with a known concentration of a second metal ion. The second metal ion must form a weaker complex with EDTA than the analyte ion so the second metal does not displace the analyte ion from its complex with EDTA. 4.Displacement titration Here the analyte is treated with an excess of a second metal bound to EDTA. The analyte ion displaces the second metal from the EDTA complex, and then the second metal is titrated with EDTA.
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.
