WitrynaThe concentration of the NaOCl in the diluted bleach solution is determined by titration with the standardized Na2S2O3. The determination involves two redox reactions: (a) The first redox reaction takes place in the flask before the titration: balance this redox reaction using the half-reaction method. WitrynaCount the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Na2S2O3 + NaOCl = Na2S2O4 + NaCl Since there is an equal number of each element in the reactants and products of Na2S2O3 + NaOCl = Na2S2O4 + NaCl, the equation is balanced. fallbrook school district calendarWitryna1 paź 2024 · Reactions between thiosulfate and hypochlorite can result in a substantial decrease in pH that in turn causes the production of bisulfite ions from thiosulfate. In turn, these ions react with chlorate ions, resulting in artificially decreased measurements of chlorate in the initial hypochlorite solutions. contract works proposal
