S is +6, O is -2
If you mean SO3^-2 (the sulfite anion), then S has an oxidation number of 4+, since each O atom is 2-. In sulfur trioxide, SO3, the S atom has an oxidation number of 6+.
+6 oxidation state
Oxidation numbers up to +7 is possible. For example: +7 for Cl in HClO4 or Cl2O7. +6 for S in SO3 or H2SO4 +5 for N in HNO3 or N2O5 +4 for C in CO2
-2 for each O +6 for S
The oxidation state of an individual sulfur atom in (SO3)2- is 4.
The oxidation number is 0 in elemental form. It can have other oxidation numbers as -2, +4 and +6 in its compounds such as H2S, SO2 and SO3 respectively.-2, 0, 2, 4 and 6 oxidation states
+6 oxidation state
If you mean SO3^-2 (the sulfite anion), then S has an oxidation number of 4+, since each O atom is 2-. In sulfur trioxide, SO3, the S atom has an oxidation number of 6+.
Oxidation numbers up to +7 is possible. For example: +7 for Cl in HClO4 or Cl2O7. +6 for S in SO3 or H2SO4 +5 for N in HNO3 or N2O5 +4 for C in CO2
+4
-2 for each O +6 for S
The oxidation state of an individual sulfur atom in (SO3)2- is 4.
-2 for each O, +6 for S
-2 for each O +6 for S
Sulfur can have a wide range of oxidation in its compounds -2 in H2S 0 in elementary sulfur (S8) +4 in SO2 +6 in SO3
The oxidation numbers in PO43- , phosphorus oxidation number=+5; oxygen = -2
There are two oxidation numbers. P shows +5 oxidation number.
