I've finally gotten around to scanning an updated copy of my Chem AA notes, so here it is!

OMG A LINK!

AHHH UPDATE! The complex ion for NH3 dissolution is [M(NH3)2x]x+, not [M(NH3)2x]x-. Basically, just change the negative sign to positive. Looks like I copied it down wrongly, sorry guys!

I've also updated the image link in the previous post, so make sure you aren't viewing the wrong version.

Changelog:
- Added complex ion formula
- Added on to anion reagents
- Corrected some reactions (according to the results we got for the trial experiment)

If you don't understand the formulae for the complex ions and the cationic equations, here's an example:

For the Cu2+ ion, when it reactions with NH3 (aq), the ionic equation is:

Cu2+ + 2OH- -> Cu(OH)2
(If you're wondering, the OH- ion didn't appear from nowhere, but actually came from aqueous ammonia, NH4OH.)

And the complex ion formed from it dissolving in excess NH3 (aq) is: [Cu(OH)4]2-

Mug hard for the upcoming triple-test whammy on Monday!
