    Yeah it looks like you're on the right track. Seems like they've given you a lot of them, as it will be pretty apparent if you do/don't understand it after the first few, let alone all of them!

    Deionised water is just water, but with nothing else in it. Pure water.

    Ammonium is the NH4+ ion for ammonia. If you take normal Ammonia, and attach another H+ to it you get ammonium.
