There is no 'sharp' end of this reaction (= all parts have unambigiously reacted with a well determined conterpart)
There are three main types of titration curves: strong acid-strong base, weak acid-strong base, and weak acid-weak base. Strong acid-strong base titration curves have a sharp and steep pH jump at the equivalence point. Weak acid-strong base titration curves have a gradual pH change around the equivalence point. Weak acid-weak base titration curves have a more complex shape with multiple equivalence points.
Phenolphthalein is commonly used as the indicator for the titration of a weak acid and a strong base. It changes color from colorless to pink at the equivalence point of the titration when the weak acid is completely neutralized by the strong base.

The types of conductometric titrations include strong acid-strong base titrations, weak acid-strong base titrations, weak base-strong acid titrations, and precipitation titrations. Conductometric titrations measure the change in electrical conductivity of a solution as a titrant is added, allowing for the determination of the endpoint of the reaction.
In a weak base-strong acid titration, the balanced chemical equation is: Base (B) Acid (H) Conjugate Acid (BH) This equation represents the reaction between the weak base (B) and the strong acid (H), resulting in the formation of the conjugate acid (BH).

a weak acid and strong base. At the equivalence point of a titration between a weak acid and a strong base, the resulting solution will have a pH greater than 7, indicating a basic solution. For the solution to be noticeably acidic at the equivalence point, it would suggest an excess of the weak acid after the reaction, which means that the acid is likely weak and not completely neutralized by the 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.
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.
Titration is the controlled neutralisation of an acid and a base. If the titration is done using a weak acid and a strong base, it can be analysed in detail and all concentrations of the aqueous species at any volume addition of the titrant can be determined.
A buffer solution in titration helps maintain a relatively constant pH during the titration process. It is composed of a weak acid and its conjugate base (or a weak base and its conjugate acid). This helps prevent large changes in pH that could affect the accuracy of the titration.
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.
To calculate the pH at the equivalence point for a titration involving a strong acid and a weak base, you can use the formula pH 7 (pKa of the weak base). This is because at the equivalence point, the solution contains only the conjugate acid of the weak base, which determines the pH.
