Q:

What is the oxidation number of sulfur in SO2?

A:

Quick Answer

The oxidation number for sulfur in SO2 is +4. To find this oxidation number, it is important to know that the sum of the oxidation numbers of atoms in compounds that are neutral must equal zero. In the compound sulfur dioxide (SO2), the oxidation number of oxygen is -2.

Full Answer

To find the oxidation number of sulfur, it is simply a matter of using the formula SO2 and writing the oxidation numbers as S = (x) and O2 = 2(-2) = -4. Using the rule and adding the oxidation numbers in the compound, the equation becomes x +(-4 ) = 0. Solving for x, it is evident that the oxidation number for sulfur is +4.

In chemical compounds, an atom's oxidation number refers to the charge that atoms have if the compound consists of only ions. When writing compound formulas or reactions, there are rules used to assign oxidation numbers.

    Is H2S polar or nonpolar?

    A:

    H2S, also known as hydrogen sulfide, is regarded as a polar molecule based on the arrangement of the hydrogen atoms around the sulfur atom and each atom's characteristics. The sulfur atom is more electronegative than the hydrogen atoms, and the bonds between the sulfur and hydrogen atoms are drawn to the sulfur atom.
