Sometimes it is not possible to indicate the end point of a titration. a) How can one proceed then and what is the name of the type of titration that can be performed? Briefly describe. An example in which this method can be used is in the determination of mercury, which forms strong complexes with EDTA, but for which there is no suitable indicator
Sometimes it is not possible to indicate the end point of a titration.
a) How can one proceed then and what is the name of the type of titration that can be performed? Briefly describe.
An example in which this method can be used is in the determination of mercury, which forms strong complexes with EDTA, but for which there is no suitable indicator that can indicate the end point.
b) You are given the task of determining the Hg2 + concentration in a sample solution? After adding an excess of EDTA, the sample solution is titrated with a magnesium solution.
20.00 ml of a 0.0452 M EDTA solution was added to 30.00 ml of sample solution
The excess EDTA was determined by adding 0.0500 M Mg 2+ solution, consuming 4.37 ml to the end point.
