idea their product contains these less eco-friendly carbons.Since "green" isn’t defined using industry or government standards‚ a cleaning supplies company can stake the environmentally-sound status of its products on a number of sorts of claims. One common way green cleaning supplies justify their eco-friendliness is by proclaiming themselves petrochemical free. Cleaning agents typically contain a lot of carbon‚ an element derived either from renewable plant sources or harmful petroleum resources

ion; it is added in excess to the oxidizing agent being determined. This would result to the formation of iodine which would be titrated with the standard thiosulfate solution. (2) For example in this experiement‚ the analyte that was used was copper in the form of CuSO4•H2O. It was strong enough to oxidize iodide ions to Iodine. The analyte was needed to be isolated‚ and we did this by precipitating it out of the solution. To precipitate out Cu (II) ions‚ NH3 was added dropwise – this is

EXPERIMENT 8 QUANTITATIVE DETERMINATION IODOMETRIC TITRATION OF COPPER CONCENTRATION IN AQUEOUS SOLUTION B Y RESULTS AND DISCUSSION Considered as moderately weak oxidizing agent‚ Iodine was used for the determination of strong reductants. Standard iodine solutions were found to have smaller electrode potentials as compared with the other oxidants‚ gaining them the advantage of imparting a degree of selectivity essential in the determination of strong reducing agents amid the presence
