DETERMINATION OF CHLORIDE ION(Cl-) CONCENTRATION IN GANGA RIVER WATER BY MOHR METHOD AT KANPUR, INDIA

Purpose of the study: The purpose of this present study was to determine the concentration of chloride ion in the water sample which collected different site and season of river Ganga. Chloride ions in the environment can come from sodium chloride or from other chloride salts such as potassium chloride, calcium chloride and magnesium chloride. Methodology: Water sample was collected from a different site(Bithor ghat, Siddnath ghat and Dhoni ghat) and different season(Pre-monsoon, Monsoon and post-monsoon) of river Ganga from Kanpur in the 2016-2018 year. Mohr method (Argentometric method) was a very simple and highly selective method for the determination of chloride ion (Cl-) using silver nitrate as the titrant. Main Findings: In both the years 2016 till 2018, chloride concentration was within the limit at testing sites. Applications of this study: To create awareness among the people to maintain the Ganga river water at its highest quality and purity levels. Originality: This project was done in the D G P G College C S J M University, Kanpur India.
