ABSTRACT:
Chloride ion – selective and platinum electrodes were successfully applied in the determination of hypochlorites in commercial bleaching solutions. The results obtained with Cl- ISE are compared to those obtained with Pt electrodes since the reactions are oxidation –reductions where the Pt responds to their potential change. A clear change and jump at equivalence points were found and titration curves are in S form which were approved by first and second derivatives. The percentages obtained with Cl- ISE are relatively larger than results with Pt electrode which are due to practical errors, interference of I- ions and little Cl- by –Product of hypochlorite manufacture. In general, almost both electrodes offered results in the range of 3-8% solutions of hypochlorites within the period of storage. Low results may by due to wasting and decomposition by temp, transferring, dilution and stirring the solution.
