The halides in unknown solution were identified as iodide and chloride based on their experimental E°(Ag/AgX) values‚ -0.16 ±0.01V and 0.22 ±0.02V respectively. These results were both accurate with percent error of 5.96% for iodine and 0.9% for chloride. The literature value of E°(Ag/AgI) and E°(Ag/AgCl) were -0.151V and 0.222V respectively (1). In addition‚ the literature vales lay within the 95% confidence interval for both halides therefore the results were accurate. These results were precise

As we saw previously‚ the water in a swimming pool needs to circulate through a filtration system to remove dirt and debris. During normal operation‚ water flows to the filtration system through the main drains at the bottom of the pool and the skimmers around the top of the pool. Minimum 70% of the water should be taken through the skimmers. New European requirements are 100% if water is injected from bottom inlets. Diagram of a swimming pool system The main drains are usually located on the
