Hello, i did a lab where i was given a sample of contaminated water
and must determine the identity of the metals and must percipitate
one out. I was able to determine the identity of metal Y which is
aluminium and metal X which is lithium. Im confused on part 3
though. lithium and alumnium are soluble in almost anything and i
cant use hydroxide or carbonate since lithium is in there, some
help please! I would also like to...

i really have no idea about this part about the solubility
generalization rules
Part B:Solubility Generalizations (up to 7 points) Copy the statements you wrote in your lab notebook here while performing the experiment. There are 7 anions and 10 cations for up to 17 statements, although you may combine some into one statement, see example on page 6. point for each correct, non-duplicated statement. You will earn 1. Example: Ionic compounds containing the carbonate ion (CO,2-) are typically insoluble...
