Does anyone know an easy way of remembering ion/anion tests?

 

[~*HSC 4 life*~]

i have trouble too

i just visually memorised the ion identification flow chart

what is ion/anion test????

is that the one with different metals forming ppt??

 

[mic_k]

the cation/anion tests are where u add like HCl and then check precipitate then add NH3 ...

I can remember the various flame tests (copper, calcium, barium) and the bright yellow precipitate for lead, but that is it. At the moment I'm hoping there will be a multiple choice question that gives us the tests.

I don't know an easy way. I know the hard way- just learn it!

I learnt using table and memorise the table visually. and of course the unique colour ppt ones and OH- ones. But i dont like this bit either. u never know wat "exam condition" do to ur brain...

I can remember the lead one, because bright yellow is pretty damn unique.

Actually just remember DONKEYS ARE NICE ... or at least that's how I do it

I just remember lead being to add Cl^- and it gives a white ppt, if you are in doubt if its silver just leave it in the sun for a few mins.

With the new modified syllabus i don't think we need to know the tests off by heart anymore

 

[Paroissien]

You are wrong there

 

[meyero]

have a look at the modifications made to the syllabus, the 'learn to' part of the anion/cation tests were all deleted.

I think all we need to know are hte experiments we did to show what anions/cations were present. But they do recommend us to know some of the tests.

shows the amendments to the syllabus and if you can't be bothered looking it up it describes how point three of page 59 was deleted, this point was the point where you had to learn all the test

But i guess we are actually competing against each other so go ahead and knock yourself out!

yeah i dont hink we actually need to knw like detail like add 5ml of hcl and then add 2 drops of watever..
i think we just need to know ys a ppt is formed.... and fgalme tests can be used!!!

 

[Paroissien]

I withdraw my comment then, but I know them anyway, and I'm still not entirely confident it won't be in there
