Ch 7: Reactions and Solutions

•1A salts, NO3-’s, acetates (CH3COO-), NH4+’s are very soluble.

•Cl-’s, Br-’s and I-’s are soluble except when combined with Ag+, Pb2+, Hg22+.

•CO32-’s, PO43-’s, S 2-’s generally insoluble (except for 1A’s and NH4+)

•OH-’s: Ba2+, 1A’s are soluble; others generally insoluble

•**The SO42-’s of Ba2+, Ag+, Ca2+, Sr2+, Pb2+are insoluble. Others are soluble.
