Answer 1

Insoluble in water:

• BaSO4

• PbCl2

• Cu2O

• AgBr

Step-by-step explanation:

Water turns out to be a good solvent for ionic substances, or in general, polarized covalent substances. On the other hand, it is not a good solvent for non-polar substances, these being the vast majority of covalent substances.
