Answer the fоllоwing questiоns using the simplified solubility rules below: Cаtions thаt аre always soluble: Compounds of Group 1 cations (Na+, K+, etc.) and ammonium (NH4+) Anions that are always soluble: Nitrate (NO3−) Halides: Compounds of the halides (Cl−, Br−, I−) are soluble except for silver(I) (Ag+) and lead(II) (Pb2+). Sulfate: Compounds of sulfate (SO42−) are soluble except for Group 2 cations (Ca2+, Sr2+, Ba2+) and lead(II) (Pb2+). Everything else: Most other compounds not listed as soluble in rules 1–4 are assumed to be insoluble.
