copper gold concentrations Solutions Just Right For You

Copper is a chemical element It is the 29th element in the periodic table Its mass number is 63 55 It is a transition metal in the middle of the periodic table The symbol for copper is Cu which comes from the Latin word cuprum which in turn came from the Latin word for the island of Cyprus where copper I'm thinking maybe at the higher concentrations your tap water is making a film of $ce{Cu(OH)2}$ on the surface of your electrode and that is what's shutting down your electroplating Your tap water might be mildly alkaline (tap water pH's can range from about $6 5$ to as high as $9 5$) Try adding a little sulfuric acid to your solutions
