Why you have to add buffer before titration with EDTA?
Adding a buffer solution before titration with EDTA helps to maintain a constant pH which is crucial for the formation of metal-EDTA complexes. The buffer solution prevents any fluctuations in pH that could affect the accuracy and precision of the titration results.
Why is a solution containing a metal ion buffered before titration with EDTA?
Buffering the solution containing a metal ion before titration with EDTA helps maintain a constant pH, which is crucial for the accuracy and precision of the titration. The buffering prevents large pH changes that could affect the formation of metal-EDTA complexes and lead to errors in the titration results.
How would the pH of the equivalence point for standard solution titration differ from a strong acid-strong base titration?
The pH at the equivalence point of a strong acid-strong base titration would be 7, as the solution is neutralized. In contrast, the pH at the equivalence point for a standard solution titration would depend on the nature of the reaction and the strengths of the acids and bases involved.
What is buffer solution in titration?
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.
Why potentiometric titration curves are s-shaped?
Potentiometric titration curves are s-shaped due to the buffering capacity of the solution. At the beginning of the titration, minimal change in pH occurs as the solution acts as a buffer, resisting pH changes. Once the buffer region is overcome, the titration curve becomes steeper as the solution approaches the equivalence point.

Why did the solution turn into light pink at the end of the titration?
The pH was changed.

What is a titration-quenching?
Titration quenching is a process where a substance is added to a solution to stop a chemical reaction or change in pH during a titration experiment. This substance helps to stabilize the solution at the endpoint of the titration, ensuring accurate results.
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
What is role of buffer solution in complexometric titration?
In complexometric titration, a buffer solution is used to maintain a constant pH throughout the titration process. This helps to ensure that the conditions are optimal for the formation of the metal-complex, leading to more accurate and reliable results. The buffer also helps to minimize the effect of changes in pH on the endpoint of the titration.
How do you use pH meter for acid base titration?
To use a pH meter for acid-base titration, first calibrate the pH meter with standard buffer solutions of known pH. During the titration, continuously monitor and record the pH of the solution as the base is added to the acid until the equivalence point is reached. The equivalence point is indicated by a sudden change in pH, which helps determine the endpoint of the titration.
How many types of indictors are used in titration?
There are two main types of indicators used in titration: color indicators and pH indicators. Color indicators change color at specific pH ranges to indicate the endpoint of the titration, while pH indicators change color based on the pH of the solution.
What is the indicator use in potentiometric titration?
The indicator used in potentiometric titrations is typically a pH electrode. By measuring changes in pH during the titration process, the endpoint of the titration can be determined accurately. The pH electrode provides a continuous measurement of the solution's pH, allowing for a precise determination of the equivalence point.
