#NO_3^-# is the nitrate ion.


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.

#O=N^(+)(O^-)_2#, i.e. the counterion to nitric acid, #O=N^(+)(O^-)(-OH)#.

What is the oxidation number of nitrogen in nitric acid?
