Hi
I was told we need to learn solubility rules. Im not sure why though... can anyone tell me??

thanks

There's no easy way. You just have to memorise it.

I managed to memorise most the solubility rules by memorising (and rote learning) the processes and steps in cation and anion testing (oddly enough). I did quite a lot of questions (HSC and trial ones) just to memorise it decently.

But if you want to memorise it the other way, being starting with solubility rules and then onto the anion and cation testing, I like using this:
Solubility rules
Gives a good overview of most ions in the syllabus. However, it is kinda hard determining the cations from that as you really only have the anions explicitly laid out.
Hope it helps

I put it in a table then memorised the table

I just memorised all the insoluble compounds - barium sulfate, silver chloride, lead chloride etc.

Rote learn.

its quite abit to remember and its rarely ever needed in the HSC so gay

Admittedly, it's very useful in university chemistry.

Check out the solubility song on youtube. Lots of versions, based around the tune "99 bottles of beer on the wall..."
Good luck,

+1 this is how i do it, but it is more helpful to also visualize the diagram in Conquering Chem or in the Student's guide to HSC chem.
