Anion identification (1 Viewer)

[Doogsy]

Whats everyones thoughts on wether they think Anion identification will be in the test. Im fine with cations as they are flame test and the pptte reactions are easy to remeber.

Well, CO3 is easy as an anion because you just add HNO3, and I think PO4 is something with KI isn't it? Geez I really need to study this ay

i thought u add calcium for co3??

 

[bloodysunday]

Nah, acid + carbonate = salt + CO2 + water. Easy

there are tables in ur text book, i have trouble rememberin them but i think CO3 is HCL and the others are different coloured precipetates with different solutions.

 

[bloodysunday]

hands up who uses "conquering chemistry" as a text book?
