a. A water solution of zinc bromide (ZnBr) and a water solution of potassium hydroxide form a water solution
of potassium bromide and a precipitate of zinc hydroxide.
b. A water solution of copper(II) sulfate and a water solution of barium chloride produce a water solution of
copper(ll) chloride and solid barium sulfate.
C. A precipitate of iron(III) carbonate and a water solution of sodium nitrate are formed when a water solution
of iron(III) nitrate and a water solution of sodium carbonate are mixed.
