The indicator added to the sample is Eriochrome
Black T. Initially, the indicator will form a complex with the cations. When complexed
it is red in color. As the EDTA is added dropwise to the sample, it replaces the Erio T
and forms more stable complexes with calcium and magnesium. When the indicator is
released by the metal ions, it has a distinct blue color. Therefore, the endpoint of the
titration is marked by the color change form red to blue

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 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 buffer solutions in complexometric titration?
Buffer solutions in complexometric titrations help to maintain a constant pH level throughout the titration process. This is important to ensure accurate results as the formation of metal complexes is highly pH-dependent. By stabilizing the pH, buffer solutions help to optimize the formation of metal complexes and improve the precision 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 the Role of ice cubes during titrations?
I think that the role of ice cubes melt by warm heat
