Hey guys just wondering....
you's reckon Finding oxidation stated to molecules would be in the HSC,
Because from all the past HSC papers i haven't seen a question based on it....
Therefore i'm probably not going to study it,

But even the more reason for them too add it this year, correct?

They've used it before in terms of: "What has been oxidised? What has been reduced?"

yea i realized.. the oxidized, and reduced terms..

but i'm talking about actually determining oxidation states of compounds,

Oxidation states should be straightforward to work out for simple compounds anyway. Generally you can work it out from individual atoms as well.
For example, H2S has an oxidation state of -2 for S and +2 for H and for the compound it is zero.

study it, will be handy for explaining galvanic cells and those discriminator questions. but now is not the time doing chemistry, maths time. EXCELLENCE!!!!
