Superior No. 75 is an inorganic acid general purpose soldering flux that can be used to solder badly oxidized copper or brass. No. 75 contains Zinc Chloride and can be soldered with a torch, in addition to a soldering iron or hot plate.

The copper sulfide reacts with air to make copper metal and sulfur dioxide. Some copper sulfide reacts with the copper(I) oxide to make copper and sulfur dioxide. This makes impure copper. Copper is made pure by electrolyzing it. A thin sheet of pure copper is put on the cathode and a thick sheet of impure copper is put on the anode.

Place the aluminum sheet placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as anode, electrolysis the aluminum sheet in the effect of certain conditions and impressed current,then it is the oxidized aluminum sheet.

Thank you for the answer. Just to clarify: So basically the patina is a non conductive coating produced as a result of the oxidized copper which would act as more of an insulator and turn lets say a 24G wire into a 30G wire; therefore increasing it's resistance and decreasing the amount of current that is .

Under the optimized conditions, copper concentrates grade of Cu % with a recovery of % was obtained through the locked cycle flotation of twice ...

Copper oxidizes over time to form a green patina, which actually protects the metal from further corrosion. Bronze is a mixture of copper and tin, along with small amounts of other elements, and is naturally much more resistant to corrosion than copper. Brass is an alloy of copper, zinc, and other elements, which also resists corrosion.

Copper metal is not generally soluble in acid because copper is a stronger reducing agent than hydrogen, that is, copper metal will not reduce H+ to H 2. Because copper is not oxidized by H+, it is inert to most acids. Aqueous nitric acid, HNO 3(aq), however, is able to dissolve copper metal because nitrate, NO3, is a powerful oxidizing agent.
