WebFor example, potassium dichromate (\(\ce{K2Cr2O7}\)) is a common oxidizing agent that can be used to oxidize alcohols (symbolized by the general formula ROH). The product of the reaction depends on the location of the OH functional group in the alcohol molecule, the relative proportions of alcohol and the dichromate ion, and reaction conditions ... WebThe quantity of potassium dichromate utilized was ascertained via titration with a predetermined volume of the steel sample. The redox reaction in question can be represented by a balanced chemical equation wherein six electrons are transferred from six iron(II) ions (Fe2+) to a single molecule of dichromate ion (Cr2O7-2), resulting in the ... fly ash for house construction backfilling
