What is the role of mordant black indicator in complexometric titration?
Mordant black indicators are used in complexometric titrations to visually signal the endpoint of the titration. They form colored complexes with metal ions, resulting in a visible color change when all the metal ions have reacted with the titrant. This color change helps in determining the endpoint of the titration accurately.
How does pH affect titration?
pH plays a crucial role in titration as it helps determine the endpoint of the reaction. The pH at the equivalence point depends on the acid-base reaction being titrated. For strong acid-strong base titrations, the pH at the equivalence point is 7; for weak acid-strong base titrations, the pH is greater than 7; and for weak base-strong acid titrations, the pH is less than 7. pH indicators can also be used to visually show the endpoint of the titration based on color change.
What is the role of phosphoric acid in titration?
Phosphoric acid is often used as a buffer in titration reactions to stabilize the pH of the solution. It helps maintain a constant pH by resisting changes in acidity when small amounts of acid or base are added during the titration process. This is important for ensuring the accuracy and precision of the titration results.
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.
What is the role of blank in formol titration?
In formol titration, blank serves as a control to account for any background color or turbidity in the sample that could interfere with the endpoint detection. By subtracting the blank value from the sample titration values, a more accurate measurement of the analyte concentration can be obtained.

What is role of muraxid in edta titrations?
Muraxid is used as an indicator in EDTA titrations to detect the endpoint of the titration when all the metal ions have been complexed by EDTA. Muraxid forms a colored complex with uncomplexed metal ions, indicating the endpoint of the titration.
What is the role of an indicator in the titration process?
An indicator in the titration process is a substance that changes color at or near the equivalence point of the reaction. It helps in determining the end point of the titration by signaling when the reaction between the analyte and titrant is complete. The choice of indicator depends on the type of titration being performed and the pH range of the reaction.
