What is the oxidation number of SO2 in ions and compound?
In a whole, sulfur dioxide molecule has oxidation number 0. Sulfur has +4 oxidation number as it is bonded with two oxygen atoms through four covalent bonds. Oxygen atoms have oxygen number of -2 each.
What is the oxidation number of sulfur in S4O6?
Regarding the oxidation states of the atoms in the tetrathionate ion: The tetrathionate polyatomic ion is made of four sulfur atoms, each with an oxidation number of +1, and six oxygen atoms each with an oxidation number of -1. Note, this is one of the rare exceptions to the 'rule' that oxygen normally has a minus two oxidation number. Other -1 oxygen compounds are the peroxides. An interesting half reaction is the oxidation of two thiosulfate ions to tetrathionate, in which sulfur has an oxidation number of +2 in the reactant and +1 in the product. Oxygen has an oxidation number of -2 in the reactant, and -1 in the product. 2S2O3-2 ----> S4O6-2 + 2 e-
What is the oxidation number for HSO4?
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.
What is the oxidation number of Ca So4?
Since the SO4-2 ions have two negative charges and oxygen atoms in almost all compounds have two negative charges each, the sulfur atoms have an oxidation number of -2 -4(-2) = +6.
What is the oxidation number of sulfur in s2o3 2-?
+6. Working this out is tricky. Not knowing the structure, and assuming each oxygen was present as O2- you would have to say -7. This is difficult to understand as S has only 6 valence electrons. The structure is actually O3SOOSO3,(see link), 6 oxide ions (oxidation number -2) and 1 peroxide ion (overall oxidation number -2, average oxygen oxidation number of -1) . Overall the oxygen atoms contribute -14, and less the charge on the ion of -2 gives the total oxidation number of both sulfur atoms as +12, so each sulfur is +6. This is a lot more sensible. S has its maximum oxidation number of +6 as it does in SO3 and SO42-.

What is the oxidation number of each ion in Sodium oxide?
Each of the two sodium atoms in the formula for sodium oxide has an oxidation number of +1, and the oxygen atom has an oxidation number of -2.
What is the oxidation number for BaSO4?
The oxidation number for BaSO4 is 6. It goes as follows: +2 for Ba +6 for S -2 for O
What is the oxidation number of sulfur in Na2S2O8?
+6 for each sulphur. +1 for each Na; Two oxygens are as peroxides and will have -1 charge / oxidation number each. Six oxygens are as oxides and will have -2 charge each. So, 2(+1) + 2y + 2(-1) + 6(-2) = 0 Or y = +6 (the charge / oxidation number of sulphur)
What is the oxidation number of sulfur if H2SO4?
+6 for S, +1 for each H, -2 for each O
What is the oxidation number of the sulfur atom in H2S?
+1 for each H and -2 for sulphur
What is the oxidation number of each element in the compound water?
The hydrogen atoms are each in the 1+ oxidation state. The oxygen is in it's 2- oxidation state.
What is the number of atoms of each element in sulfur dioxide?
1 Sulfur atom and 2 oxygen atoms. Its molecular formula is SO2
