Cupric iodate, Cu(IO₃)₂

Solution of cupric hydroxide or carbonate in a solution of iodic acid yields the Cu(IO₃)₂, which is known in the anhydrous form, and as monohydrate, and dihydrate. From excess of a solution of potassium iodate, cupric nitrate precipitates the pale-blue monohydrate. At 25° C. its solubility is 3.3×10^-3 gram-molecules per litre of water. A basic iodate, Cu(IO₃)₂,Cu(OH)₂, has also been prepared.
