The end point in an acid-base titration is the point at which an indicator changes color and signifies that equivalence has been reached between the acid and base being titrated. This is when the amount of acid and base are in stoichiometric proportions.

What is the stoichiometric point of a titration called?
The stoichiometric point of a titration is called the equivalence point. At this point, the moles of acid and base have reacted in exact stoichiometric proportions, resulting in complete neutralization.
How do you get sharp end point in acid-base titration?
To get a sharp end point in an acid-base titration, it is important to add the titrant (acid or base) drop by drop near the expected end point, which is determined using an indicator. The indicator will change color when the solution reaches the end point, indicating that the reaction is complete. Slowly adding the titrant near the end point helps to achieve a sharp color change and precise determination of the equivalence point.
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?
This point is called the endpoint of the titration. It is the stage at which the reaction between the acid and base is considered complete, based on the color change of the indicator.
How do you determine the end point from titration in acid base titration process?
The end point in acid-base titration is usually determined using an indicator that changes color at the equivalence point. Common indicators include phenolphthalein and methyl orange. The end point is reached when the color of the indicator changes permanently, signaling that the reaction is complete.
What does a titration graph of a weak acid with a strong base look like?
In the titration of a weak acid with a strong base, the pH initially remains relatively constant as the strong base is added, due to the buffer effect of the weak acid and its conjugate base. As the equivalence point is approached, the pH starts to increase more rapidly. At the equivalence point, the pH jumps to a higher value due to the neutralization of the weak acid by the strong base.

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.

Will the solution at the end point of an acidbase titration be acidic neutral or alkaline if it is a weak acid and strong base?
The solution at the endpoint of an acid-base titration involving a weak acid and a strong base will be alkaline. This is because the weak acid will have been neutralized by the strong base, resulting in excess hydroxide ions in the solution causing it to be alkaline.
Why titration of weak acid and weak base are not done?
Titration of weak acid and weak base is not typically performed because the equivalence point is difficult to determine due to the buffering capacity of the solution at the equivalence point. The pH at the equivalence point for weak acid and weak base titrations may not be close to 7, making it challenging to accurately detect the endpoint.
Why did the solution turn to pink at the of the titration?
because the solution react with sulphuric acid. other than that, the end point is indicated.
What is the relationship of the successive equivalence point volumes in the titration of polyprotic acid?
the end point will be a simple multiple of the first
Describe a method to visually detect the end point of a titration without the use of instruments?
One way to visually detect the end point of a titration without instruments is to use an indicator that changes color at the equivalence point. For example, phenolphthalein changes from pink to colorless at the endpoint of an acid-base titration. Another method is to add the titrant drop by drop and look for a sudden color change in the solution.
Can pH meter can be used for acid base titration?
Yes, a pH meter can be used for acid-base titrations by measuring the pH of the solution being titrated as the titrant is added. This can help determine the equivalence point of the titration when the pH changes sharply, indicating the end point. It is important to calibrate the pH meter properly and use it in conjunction with appropriate indicators for accurate results.
