What is role of buffer solution in complexometric titration?
buffer solutions resists change in PH
Why buffer solution must be used for titration with EDTA?
Because it dissolves prcipitate that form after addion of sodium hydroxide.
What is the role of buffer solutions in complexometric titration?
Buffer solutions resist the change in PH
A solution that is resistant to change in pH?
Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.
What is pseudo buffer?
a solution which does not fulfills the property of a buffer solution but act as buffer solution.

What is the need for an ammonical buffer solution in the determination of hardness of water by edta titration?
during the complexometric titration using edta it is very necessary to maintain the ph of the solution near about 10 so we use ammonium chloride buffer if we will not use this buffer dring the titration ph of sol. will ho lower side

Why titration of weak acids and weak bases are not done?
It is difficult to determine the end point of such a titration, because the titration produces a buffer solution that changes its pH very slowly at the end point, in contrast to reaction between a strong acid and strong base.

Why does the pH drop so fast during titration at a certain point?
When there is a buffer present, the buffer makes it difficult to change the pH of a solution. Say for instance a buffer keeps the pH around 6.5 +/- 0.2 . The buffer only works when the pH is in this range. If too much acid or too much base is added, taking the pH out of this range the pH will change quickly, even if only a little extra base or acid is added to the solution.
Why titrations of weak acids and weak bases are not done?
It is difficult to determine the end point of such a titration, because the titration produces a buffer solution that changes its pH very slowly at the end point, in contrast to reaction between a strong acid and strong base.
What is Over titration?
Over titration occurs when an excess of one solution, known as a titrant, is added to another solution. Titration is done to know the amount of solution to be added to reach neutralization.
What is meant by titrant in titration?
The titrant is the solution involved or used in a titration to determine the concentration of an unknown solution.
What happens when HCl is mixed with a solution that is not a buffer solution?
If the solution is not a buffer, the HCl will react with the solution to form a product.
