On page 106 of the workbook are two oxidation-reduction reactions. We discussed the first one (KClO3 and H4N2) and determined the oxidizing agent and the reducing agent as well as which substance was oxidized and which was reduced. There is an example in the text (example 3.9) that does this as well. This quiz question asks you to do this for the second reaction on page 106. Group of answer choices HNO2 is the reducing agent and it is reduced while CrO42- is the oxidizing agent and it is oxidized. HNO2 is the oxidizing agent and it is oxidized while CrO42- is the reducing agent and it is reduced. HNO2 is the oxidizing agent and it is reduced while CrO42- is the reducing agent and it is oxidized. HNO2 is the reducing agent and it is oxidized while CrO42- is the oxidizing agent and it is reduced.
