Question

Which are true and which are false?


-The copper(I) ion is colorless
-Copper(I) chloride is soluble in water.
-Both oxidation process, Cu metal to Cu+, and Cu metal to Cu2+, require energy.
-If your product is greenish in color, it contains Cu(II) ions as impurity.
-The reaction of Cu metal with Cu2+ is called disproportionation.
-The most stable oxidation state of copper is +2.
-The Cu+ ion has a greater solvation energy than the Cu2+ ion.
-It is easier to oxidize Cu(I) to Cu(II) than it is to oxidize Cu to Cu(I).
