Argentometric determination of chloride content in tap water at Gimba city administration, South wollo, Ethiopia

Background This study investigates chloride concentrations in tap water samples from Gimba city administration, using the argentometric method to assess water quality. Chloride levels are a key indicator of water treatment effectiveness, particularly the adequacy of chlorination, which is critical for preventing waterborne diseases. Methods Chloride concentrations in tap water samples from various locations in Gimba city administration, were determined using the argentometric titration method. Silver nitrate (AgNO₃) was employed as the titrant to precisely quantify chloride ions. The water samples were collected from different sites in Gimba, and chloride levels were measured to evaluate the adequacy of water treatment processes. Results The chloride concentrations across all samples ranged from 52.8 mg/L to 71.9 mg/L, well below the World Health Organization’s recommended limit for drinking water. Significant variation in chloride levels was observed, with Dembesh exhibiting the highest concentration and Medera the lowest. Conclusion The low chloride concentrations suggest insufficient chlorination at the sampling sites, which may compromise the effectiveness of water disinfection and contribute to the prevalence of waterborne diseases in the region. The study underscores the need for enhanced water treatment and disinfection practices in Gimba city to ensure safe drinking water and reduce health risks.
