Updated Chem AA
Posted by LZC at 10:09 PM
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! |
