Useful mnemonics for Science Exams?

Yea our teacher taught us that and everyone was laughing lol. Anything else useful? I can't remember the stupid negative ion test - you know the silver nitrate solution and the barium chloride.. AHHHHHHHHHHHHHh

(If you cont. chemistry, you will learn why the ppt. barium sulphate is insoluble.)

Because it feels like it :P No serious why is it insoluble. Do we need to know this!

Solution enthalpy = Hydration enthalpy - Lattice enthalpy

In barium sulphate, lattice enthalpy > hydration enthalpy. So solution enthalpy relatively endothermic.

I used the very helpful acronym, ACPN - Anode Cathode Positive Negative. :P

Btw, I don't think ACPN stands for anything else - I was just bored while revising GCSE Chemistry and wrote ACPN about a hundred times on a piece of paper. ^_^

not a mnemonic but my teacher taught us this:

The "Pussitive" ions go from the Cation

- takes the bore off ecology - not much though.
