WebIt is possible to determine the concentration of hypochlorite in bleach in the laboratory using a 2 step process: 1. Hypochlorite is converted to chloride in the presence of excess iodide, producing brown-coloured iodine molecules. 2. Redox titration of iodine molecules using aqueous sodium thiosulfate solution. WebJan 30, 2024 · In terms of hydronium ion concentration, the equation to determine the pH of an aqueous solution is: \[pH = -\log[H_{3}O^+]\] pOH : The pOH of an aqueous solution, which is related to the pH, can be determined by the following equation: \[pOH = -\log[OH^-]\] This equation uses the hydroxide concentration of an aqueous solution instead of the ...
