Oh I was just asking ahaha
Anyways if anyone here is generous enough could you please explain to me spetator ions, ionic equations, half equations, OILRIG, etc all with examples (if it's too much do 1-2 at a time). I seriously suck at those and I want to continue chemistry in year 12 (I heard it comes up in year 12 BTW and that's the main reason why I'm worried)
Thanks so much
Alright, although this is a question, you should probably have a go at these first. A simple google search, or using a textbook would give you the answers.
Spectator ions don't participate in the reaction. So if have like a compound like sodium sulfate and barium nitrate, the precipitate would be barium sulphate, the sodium ions and nitrate ions are spectator ions as they are not involved in the main reaction, but they are in the solution.
Ionic equations are kind of self explanatory. If you have a specific question about it, I can elaborate.
Half equations: One for oxidation and another for reduction since both occur spontaneously.
OILRIG is just oxidation is losing electrons. Reduction is gaining electrons.
Alright examples you don't really need at this point. But since you're keen on learning this (it does indeed come up in year 12), you should check out videos from Khan Academy, or other youtube sites because they introduce you to the basics. These basics will suffice for year 11 and year 12. If you have any specific question after that, I'd be happy to answer it.
