What would happen when sulphuric acid is not added in spectrophotometric titration?
If sulfuric acid is not added in spectrophotometric titration, the acidic conditions required for the reaction between the analyte and the titrant may not be met. This could lead to inaccurate results or incomplete reaction, affecting the precision and reliability of the titration. Additionally, the absence of sulfuric acid may alter the chemistry of the system and prevent the formation of the colored complex that is usually measured in spectrophotometric titrations.
Can you determine strength of more than one colored complex using spectrophotometric titieration?
If the the colored complexes do not have heavily overlapping emissions spectrums, yes, it is possible. It really depends on how you are measuring it, what you are looking for, what contaminants you might have, and how accurate/well calibrated your equipment is.
Why is not possible to determine iodide by mohr titration?
Iodide cannot be determined by Mohr titration because it does not form a precipitate with silver nitrate. Mohr titration relies on the formation of a colored precipitate to indicate the end point, which is not observed in the case of iodide ions. Other methods, such as iodometric titration or spectrophotometry, are used to determine iodide ions quantitatively.
What is the aim of a thermometric titration?
The aim of a thermometric titration is to measure the heat change that occurs during a titration reaction. This can be used to determine the endpoint of the titration, as it corresponds to the point of maximum or minimum heat change. Thermometric titrations are useful for studying reactions that do not produce a visible change in color or involve weakly-colored solutions.
What is the purpose of Volhard titration?
The purpose of Volhard titration is to determine the concentration of halide ions (such as chloride, bromide, or iodide) in a solution by titrating with a standardized silver nitrate solution. The endpoint of the titration is indicated by the formation of a colored precipitate of silver halide.
What is complexometry?
A chemical technique using the formation of a colored complex to indicate the end of a titration.
What is compleximetric titiration?
Complexometric titration is also known as chelatometry. It is a form of volumetric analysis in which the formation of a colored complex is used to indicate a titration's end point.
What happens to the color of the Fe2 when the equivalence point is reached in a titration?
When the equivalence point is reached in a titration, the color of Fe2 changes because it reacts with the titrant to form a different colored compound.
How do you find out the concentration of a colored solution without titration or colorimetry?

What is the role of KI in the estimation of aniline?
ki is added to liberate iodine gas . this liberated iodine gas was then titrated with sodium thiosulphate to give a permanent white precipitate. this white precipitate indicates the endpoint of the titration..
What is the function of white tile in the acid-base titration experiment?
In an acid-base titration experiment, a white tile is used to provide a neutral background against which to observe color changes, making it easier to accurately detect the endpoint of the titration when using colored indicators. The white tile helps to enhance the visibility and contrast of color changes, allowing for more precise titration results.
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.
