Answer / karri.sureshkumar07
hardness means presence of Calcium and Magnesium carbonates
and bicarbonates, these can be analysed by titration with
EDTA ( Ethylene Diamino tetra acetic acid ) using muroxide
and Eriochrome black-T as indicators
For calcium hardness muroxide is the indicator colour
change is pink to violet ( brinjal flower colour)
For total hardness determination EBT is the indicator
colour cange is pink to blue
