Hey guys, just looking over my stuff for tommorow when I realise I'm not really all that great on identifying unknown Ions. i think ive got the anion one down:
start with PO₄^3-, CO₃^2-, SO₄^2-,Cl^2-.
add AgNo₃
yellow precipitate shows PO₄^3-
white - everything else
Add BaNO₃
No precipitate - Cl^2-
Precipitate - everything else
add an Acid
bubbles-CO₃^2-
no bubbles-SO₄^2-

Do we need it in this much detail, and is that all correct etc, and if so, can someone pelase link me to the cation one?
and I'm also kinda stuck on the flame testing and solubility rules.
thanks in advance (I hope)
