dc.description.abstract The treatment of drinking water is crucial to ensure public health safety. Bleach, or sodium hypochlorite, is commonly used as a disinfectant due to its effective antimicrobial properties. However, its decomposition over time can reduce its effectiveness. In our study, we addressed various aspects related to bleach, including its composition, stability, quality, and effectiveness as a disinfectant. Through various dosage methods such as spectrophotometry, pH-metry, and iodometry, we determined the concentrations of the main ions present in bleach, including hypochlorite ions. The results obtained revealed significant variations between the different dosage methods used, highlighting the importance of choosing the appropriate method based on specific analysis needs. Additionally, we identified the presence of ions coexisting with hypochlorite in bleach solution, such as chloride, chlorate, and chlorite ions, suggesting possible product degradation and emphasizing the importance of continuous monitoring of its stability By studying the decomposition kinetics of bleach as a function of temperature, we were able to determine the order and rate constant of this reaction, and estimate the half-life of Bleach, allowing us to evaluate the effect of temperature on its stability. Finally, by simulating a three-month storage period at room temperature, we observed a significant decrease in bleach concentration, highlighting the importance of proper storage to maintain its disinfectant effectiveness These results provide valuable information to ensure the quality and safety of bleach in various applications, thereby contributing to the protection of public health and the environment. en_US
