    Can someone explain to me why this is called monohydrogen phosphate instead of hydrogen phosphate?

      I know this is three years late but mono means one. Mono hydrogen is because one hydrogen I think

      @@azyle2104 If you recall, Hydrogen never exists individually because its just not naturally possible so it always exists in a paired form, so we always write hydrogen as H2 to represent it symbolically. So now that you know it exists in diatomic form (an atom that exists in a paired form), you can notice how most of the compunds its in, its always in a diatomic form, for eg., h20 or h202, but since its in a monoatomic form in HPO42 (monoatomic means an atom existing individually), we specifically denote it as monohydrogen phosphate meaning a phosphate with a single individually existing hydrogen.
