What is the aim of the experiment described in the text?
The aim of the experiment is the determination of Total Hardness of supplied hard water sample by EDTA method.
What is the principle of complexometric titration used in the experiment?
What is the principle of complexometric titration used in the experiment?
The principle is that the Disodium salt of EDTA reacts with hard water and consumes all the hardness producing cations in alkaline medium, and the excess of this reagent is indicated by the reaction of the indicator Eriochrome Black-T (EBT).
