Since by titration we can be just acknowledged about the hardness of water…and if the hardness of water is high which corresponds to high mineral content say salts of Mg ++ and Ca++ . Moreover salty water is considered to me more hard as compared to pprtable water.

EDTA(Ethylene Diamine Tetra Acetic Acid) is a weak acid having molecular mass of 372.24 g . It has pH of 8 ; since it is a secondary standard solution , it pH increases with increase in temperature. It is a complexing agent having high affinity towards Ca ++ and Mg 2+ during this titration.
Hope you got your answer.
Thanks for reading upto this line
