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.

The point at which a drop of base changes the color of an acid solution and the color persists?
titration
What will happen to the molarity of NaOH If a drop of NaOH falls out of the flask during the titration?
You have to realise that a drop from the burette for instance is insignificant, if you are dealing with at least 10ml solution which you usually deal with on a titration. If you don't want to regard it as insignificant, then if NaOH is in the burette, then the solution doesn't become more concentrated with NaOH because that drop escaped.
What is difference between melting point and drop melting point?
No basic Difference between melting point and Drop point.
What is the meaning of the term end point in titration and what is true about the system at the end point?
In titrations, the end point is when you have brought the tested sample to absolute neutral. At this point, if you add one more drop of titrating solution to the sample, you would change the pH sufficient to change the color of the indicator in the sample. This is the point at which you can determine the pH of the original solution, by calculating back the amount of titrating solution you had to add to the sample to neutralize it.
What is titration in chemistry?
Completely titrated means it reached the stoichiometric point (usually pH=7). Simply means neutralized.
The point at which a drop of base changes the color of an acid solution and the color persists?
titration
In a titration the point at which one drop of base turns the acid plus indicator a pink color that lasts for 30 seconds is called the?
The end-point
Why the titration process should be done drop by drop?
Around the expected equivalence point of the titration, you need to drop the solution very slowly and mix the solutions very well because, around the equivalence point, just one drop of solution from the buret can make a radical pH change in the mixed solution. If the color of the solution in the erlenmeyer flask changes, record the volume of the solution in the buret and add a few drops of the solution to make sure the the equivalence point you found is correct.

What is the name of the process when you combine an acid with a base?
Titration. You add it one drop at a time...
Can a strong base be a biurette solution in titration?
No, because a drop of strong base can change the pH a lot and mess up titration, it has to be a moderate-weak base!
Why you use tritation?
there are many uses of titration..to know the volume of one drop of a liquid..
What is difference between melting point and drop melting point?
No basic Difference between melting point and Drop point.
What are the advantages and disadvantages of acid base titration?
Advantages:Simple to doCost effectiveDo not need high expertisevery accurate and preciseCan be used by low skilled traineesDisadvantages:Determining end point may be difficult (pending indicator used)Requires careful attention to reach end point accurately (based on split-drop method)

When performing titrations why should you constantly stir the contents?
During a titration, reactant from the burette are added drop wise. It may not reach the bottom, which might result in an incorrect endpoint. The flask is always stirred to mix the reactants in the flask evenly.
What is the meaning of the term end point in titration and what is true about the system at the end point?
In titrations, the end point is when you have brought the tested sample to absolute neutral. At this point, if you add one more drop of titrating solution to the sample, you would change the pH sufficient to change the color of the indicator in the sample. This is the point at which you can determine the pH of the original solution, by calculating back the amount of titrating solution you had to add to the sample to neutralize it.
