ANION TEST

Any kool ways to remember anion test for

HALIDES
NITRATE

sweetsh:
I dont have a "cool" way.
But its simply that:
Cl- : with HNO3 and AgNO3 -> white ppt
                                               with HNO3 and Pb(NO3)2 -> white ppt

Br- : with HNO3 and AgNO3 -> pale yellow ppt
                                                 with HNO3 and Pb(NO3)2 -> pale yellow ppt     

I-: with HNO3 and AgNO3 -> yellow ppt.
                                                  with HNO3 and Pb(NO3)2 -> yellow ppt.


For (NO3)- :
1) add NaOH
2)Add Al particles(powder foils or granuels)
3)put a damp red litmus on the mouth of the test tube.
4)warm gently

Result:
1)pungent smell
2) red litmus paper will then turn to blue
beacuase NH3 is formed
