EDTA method for the determination of hardness a complexometric method

Ethylene Diamine Tetra Acidic acid is very useful tetra protic acid for determination of hardness as it's anion is reactive on positive charge ion from the hardness causing salt. Hence it is called as a complexometric reagent. And the reaction is complexometric reaction. #hardness #hardnesstesting ,#water #chemistry #science #education #edta #chemistryengineering
