Ques 9Environmental Engineering

The hardness of a water sample is measured directly by titration with 0.01 M solution of ethylenediamin etetraacetic acid (EDTA) using eriochrome black T (EBT) as an indicator. The EBT reacts and forms complexes with divalent metallic cations present in the water. During titration, the EDTA replaces the EBT in the complex. When the replacement of EBT is complete at the end point of the titration, the colour of the solution changes from

a. blue to colourless
b. blue-green to reddish brown
c. wine red to blue
d. reddish brown to pinkish yellow
