One thing in chemistry I've never been able to get my head around is ionic equasions, I don't see how they work. I mean, I'm told to only use the ions involved in the reactions and leave out spectator ions, but how do I tell which is which?
I know that they're similar to half-equasions in REDOX reactions, but I'm not sure if I fully understand them either XD
If anyone could explain it to me in simple terms it would be greatly appreciated.
