\Why is it useful to use an indicator in this titration of edta and fe (III)? What would be the consequence if an indicator was not used? (5 pts)

Step 1
In the titration of EDTA with Fe(III), the indicator helps to visually signal the endpoint of the titration, which is crucial for determining the exact point at which all the Fe(III) ions have reacted with the EDTA. Show more…

Some titrations are done using indicators, substances that change color when hydrogen ions are added t0 or taken away from the indicator molecule_ The color change indicates the endpoint of the titration. Why isn an indicator used in this titration? Reactions that involve electron transfer happen at very diflerent rates- depending on the substances involved in the reaction and the solvent Some happen as many as 10* times per second, and some happen billions of times slower: From practical point of view. does matter how fast reaction occurs in titration? Explain. Suppose you titrated the iron sample with 0.20 M KMnO4 instead of 0.020 M KMnO+ How would this affect the volume of' solution used? How would this affect the accuracy of' your titration?

Concerning EDTA titrations, which of the following is correct? EDTA forms 1:2 complexes with metal ions. The most widely used indicators are murexide and Eriochrome Black T. In the presence of NaOH, EDTA reacts only with Mg+2 ions, using murexide indicator. The water hardness is usually expressed as MgCO3 mg/L water. EDTA solution was standardized using NaCl.
