Finding Oxidation Numbers

[therubixman]

Thank you, but I have a question, what if you have a compound like CaSO4?

@therubixman Sorry this took so long. For a compound with a polyatomic ion in it you can use your table to see that SO4 has an overall 2- charge. From there you can work out S from O having an oxidation number of -2. -2 x 4 Oxygens = -8 and the overall polyatomic ion is 2- so S must be +6. With the O and the S done Ca must be +2 since CaSO4 has no overall charge

Hey man thanks, I couldn't understand this until I was able to slow it down a bit. Really helped.

Thank you very much! I´ve searched and watched so many videos. Your expöanation was simple and understandable(without this I wouldn´t have understood this). Thanks!

very well explained thanks

This was the best video explanation I've encountered!!! I've watched so many and this one was the best one that left me understanding how to find oxidation numbers!!

That is by far the best explanation I have seen on solving oxidation numbers! Thanks!

[TheEmpireOfEuphoria]

Of all the tutorials i've watched, this explained it to me the best. Thanks !

it wudve been much better if u used the familiar method of solving an x equation! ur way is a bit complicating :\
