Determine the oxidation states of elements in substances whose formulas are Na2s, SO2, H2

When arranging the oxidation states in compounds, it must be remembered that the compound must be electrically neutral.

1) Na2S – the oxidation state of sodium Na (+1), the oxidation state of sulfur S (-2).

2) SO2 – oxidation state of oxygen O (-2), oxidation state of sulfur S (+4).

3) H2 is the oxidation state of hydrogen H (0).
