Would someone be kind enough and tell me the tests for

-CO3 (2-) . HCO3 (1-)
-NO3(1-)
-NH4(1+)

NH₃ in solution is partially NH4OH, so i guess the tests could overlap. roughly though, to show that there is ammonia in solution, add a few drops of the solution to some copper (II) ions in sol'n, should give a ppt, then add some more of the soln, if there is ammonia, then the ppt will redissolve to give a deep blue solution.

ammonium: heat with NaOH, test gas with damp red litmus.

NO₃^-: heat with NaOH, test any gases with damp litmus paper, then add devardas alloy, continue heating. if ammonia is released AFTER the devardas alloy is added, then you have nitrate.
