The hardness of a water sample is measured directly by titration with 0.01 M solution of ethylene diamine tetraacetic 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 complete at the end point of the titration. The colour of the solution changes from  
  • a)
    Reddish brown to Pinkish yellow  
  • b)
    Blue to colourless  
  • c)
    Wine red to blue    
  • d)
    Blue - green to reddish brown
Correct answer is option 'C'. Can you explain this answer?
