When testing for ions, can you add other tests to other tests
E.g. I have to identify between sodium carbonate, sodium chloride, sodium sulfate and ammonium chloride, can I do the;
Nitric acid test for carbonate ions
Then barium chloride test for sulfate ions
Then sodium hydroxide to test for ammonia
Can I add one test on top of another (have to do the experiment in as few tests as possible)
Thanks 😌
I have done the graft just stuck at the last hurdle!!!

But the ions still exist?

IF you then added Ba2+ and it didn't make a white ppt, you know you haven't got a sulfate.
IF you then added NaOH, wouldn't it just react with the nitric? IF you added an excess of OH-, it'd precipitate the Ba2+. IF you added enough OH-, it might allow you to test for NH4+.
Don't even think about adding Ag+ on top.
MUCH easier to use a new test tube.
