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.

Why need to add reagent drop by drop during titration?
Adding reagent drop by drop during titration allows for precise control of the reaction and helps prevent over-titration. This ensures that the endpoint is accurately determined and the titration results are as precise and reliable as possible.
What is the name of the process when you combine an acid with a base?
Titration. You add it one drop at a time...
How do you get an accurate titration?
In Titration, to make sure we get a reliable and accurate result at first we will do a rough titration and we would do this by balancing the weigh boat to 0.00, use exact 2.5g of potassium carbonate, make sure the stopper your using is not broken and test it before using it. Look carefully at position of meniscus and it should be read from eye level. Raising the burette and glass pipette for every activity will help to reduce contamination, by doing these procedures we will get accurate results. After 25.9 cm make it drop by drop, to reduce the human error, there should be more than one person to do the experiment so they can get the timing right. Before using the conical flask, water it with distilled water
Why is it important to obtain the end point with just one drop from the burrete?
Obtaining the endpoint with just one drop from the burette helps increase the accuracy of the titration. This minimizes the chances of overshooting the endpoint and ensures precise determination of the volume of titrant needed to reach the endpoint. It also reduces the margin of error in the titration results.
Can a strong base be a biurette solution in titration?
Yes, a strong base can be used as the titrant solution in a titration, typically in an acid-base titration. The strong base is gradually added from the burette to neutralize the acid in the solution being titrated. This allows for the determination of the unknown concentration or volume of the acid solution.

Why you use tritation?
there are many uses of titration..to know the volume of one drop of a liquid..
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.
Describe a method to visually detect the end point of a titration without the use of instruments?
The method used most often in chemistry labs is by use of a pH indicator in the sample being titrated. When you reach the titration point, the indicator will change colors, demonstrating the end point of the titration.

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
The point at which a drop of base changes the color of an acid solution and the color persists?
This point is known as the endpoint in a titration. It signifies that the reaction between the acid and base is complete. The color change usually happens due to the addition of an indicator, which changes color at a specific pH.

What happens when a drop remains hanging from the tip of the burette after the solution has been added to the flask?
If a drop remains hanging from the tip of the burette after the solution has been added to the flask, it could lead to inaccuracies in the volume measurement since that drop has not been delivered into the flask. To ensure accurate measurements, it is important to wait until the drop completely detaches from the tip before stopping the titration.
