Title: oxidation numbers
Post by: vwinnie8 on April 25, 2011, 02:27:39 pm
If there's a number in front of a compound, such as, 2SO2, what would the oxidation number for it be?

The oxidation number of the element in a compound doesn't change because of its stoichiometric ratio (i.e. the number in front of its formula). So in sulfur dioxide, the S would still have an oxidation state of +4 and the O would still have an oxidation of -2 whether it's 2SO2, or 3SO2 etc.
