Consider the following unbalanced redox reaction: SCN (ag) + OCI (ag) 2 SO²-(ag) + CO3?- (aq) + NO3 (ag) + Cl(ag) a. What is the oxidation number for the sulfur atom in SO42-? What is the oxidation number for the carbon atom in CO32-? What is the oxidation number for the nitrogen atom in NO3-? b. If the carbon atom and nitrogen atom in SCN are arbitrarily assigned the same oxidation numbers as found in CO32- and NO3 , respectively, what must the oxidation number be for the sulfur atom in SCN-? C. Balance the reaction in basic solution.
