The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula H C O 3 â and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.
The sulfur atom is in the +6 oxidation state while the four oxygen atoms are each in the â2 state. The sulfate ion carries a negative two charge and is the conjugate base of the bisulfate (or hydrogen sulfate) ion, HSO 4 â , which is the conjugate base of H 2SO 4, sulfuric acid.he sulfur atom is in the +6 oxidation state while the four oxygen atoms are each in the â2 state.
