The oxidation number of oxygen in oxyanions such as this is usually considered to be -2.
The oxidation state of sulfur in HSO4-2 is +6. In the sulfate ion (SO4-2), oxygen is assigned an oxidation state of -2. Since the overall charge of HSO4-2 is -2, the oxidation state of sulfur must be +6 to balance the charges.
H2SO4 is a compound and as such does not have an oxidation number. The individual atoms in this compound have oxidation number +1 for each hydrogen atom, +6 for sulfur, and -2 for each oxygen atom.
Number for hydrogen is +1.Number for sulphur is +6.Number for oxygen is -2.The oxidation number for the overall ion is -1. Oxidation numbers for hydrogen and oxygen are +1 and -2 respectively. By balancing the charges, the sulfur atom is in +6 state.
The oxidation number of sulfur in the bisulfate ion (HSO4-) is +6. Sulfur typically has an oxidation number of -2 in sulfates (SO4 2-) and gains an additional oxygen atom in bisulfate, hence the oxidation number of +6.
The oxidation number of sulfur in sodium bisulfate is +5. In bisulfate ion (HSO4-), the overall charge is -1, so the oxidation number of sulfur can be calculated as -1, taking into account the oxidation number of sodium as +1.
The oxidation state of sulfur in HSO4-2 is +6. In the sulfate ion (SO4-2), oxygen is assigned an oxidation state of -2. Since the overall charge of HSO4-2 is -2, the oxidation state of sulfur must be +6 to balance the charges.
In HSO4- sulfur's oxidation state is +5.

+6: Except in peroxides and superoxides, oxygen in compounds always has a formal oxidation number of -2, and hydrogen in salts or acid anions such as this has a formal oxidation number of +1. S must therefore have a value of +6 in this acid anion, to result in the total of -8 from four oxygen atoms and the +1 from hydrogen having a total charge of -1 for the acid anion.
The name of the HSO4 2- ion is hydrogen sulfate or bisulfate ion.
biSulfate ion or Hydrogen Sulfate
H2SO4 is already a strong acid.If you mean what is the conjugate base, then the answer is HSO4-
HSO4- is a weak acid. It is the conjugate base of sulfuric acid (H2SO4), which is a strong acid. However, HSO4- itself is a weak acid and partially dissociates in water.
The formula for copper(I) hydrogen sulfate is CuHSO4. This compound contains copper in the +1 oxidation state, hydrogen, sulfur, and oxygen ions.
