In oxygen containing anions that also include a less electronegative element, oxygen is taken to have an oxidation number of -2. A sulfate ion has a charge of -2. The four oxygen atoms of a sulfate ion have a total charge of 4 X -2 or -8; therefore, the oxygen atom must have an oxidation number of +6 to yield the correct value for the charge of the sulfate ions.
The oxidation number of sulphur in H2S is 2.
Oxidation no of sulphur is +2.
6+
Oxygen atoms are generally considered to have an oxidation number of -2 in all oxyanions such as sulfate.
+6 for sulfur in sulfates
The oxidation number of sulphur in H2S is 2.
Sulphur has 6 valence electrons. So its maximum oxidation number is +6.
Oxidation no of sulphur is +2.
6+
Oxygen atoms are generally considered to have an oxidation number of -2 in all oxyanions such as sulfate.
The oxidation number in atomic sulfur is 0. The oxidation number of sulfide ion is -2. With oxygen and other non metals, it makes numerous ions where its oxidation number varies from -2 to +6.
Things are complicated if we use the term valency. It is better to use the term Oxidation state or Oxidation Number. In SO2, the oxidation state of sulphur is +4 and In SO3, the oxidation state of sulphur is +6.
+6 for sulfur in sulfates
There is no oxidation number for compounds, only the elements within compounds. The charge of SO4 (sulfate) is 2-. The oxidation number of each oxygen is 2-. The oxidation number of the sulfur in this compound is 6+.
Atomic sulfur has oxidation number 0. The oxidation number of the sulfide ion is -2. During formation of a wide variety of compounds, the oxidation status of sulfur may differ from -2 to +6.
+4 for carbon, -2 for each Sulphur
6. The oxidation number of sulfur is +6. Another approach if you are not familiar with oxidation number is to draw Lewis dot diagrams for sulfate ion, these will have 2 double bonds and two single bonds (single bonds attaching negative charged oxygen atoms) and will show will show 6 bonds from sulfur.
