How would you name the following polyatomic ion: NO3-?
Nitrate is the counterion of nitric acid. Nitrate salts tend to be soluble in aqueous solution. The Lewis structure of nitrate ion is interesting because a formal positive charge lies on the nitrogen, and 2 formal negative charges are carried by the oxygens. This Lewis structure need not be known at A levels.
What is the oxidation number of nitrogen in nitric acid?
