it seems like so much to remember, do i need to know it all?
i dont think you need to know all of them, just the main ones(potassium, sodium,copper, soething else) and a few of the precipatates
it's best if you revise all of them, when I did mine they asked for quite a few tests and you just never know which ones will come up.
yep, revise all of them, they always come up. Precipitates as well. I've just created a quiz that has everything on the foundation tier on it including flame tests+precipitates.
If you want, try and make up a sentence out of the colours.
Barium, apple green
Al3+, Ca2+, Mg2+ - all white
Cu2+ - Blue
Fe2+ - Green
Fe3+ - Brown (rust)
just trying to help!
