Electrolysis of CuSO4 with copper electrodes?

2011/10/19So we performed a series of electrolysis (of CuSO4 with Cu electrodes) experiments with different currents and calculated the mass of copper lost at the anode and deposited at the cathode each time. I thought the mass of copper lost at the anode was supposed to be equal to that gained at the cathode but in all 6 cases the mass of copper deposited on the cathode was greater than the mass

Electrowinning Copper Chemistry Tutorial

Electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore. Copper occurs on Earth both as native copper (the uncombined element, Cu), and in ores (copper compounds, or mixtures of compounds, from which copper metal can

A Study of the Heat Effects at Electrodes During

2014/10/8Temperature difference measurements were made during the electrolysis of aqueous copper sulfate between copper electrodes. The temperature differences measured were those between the cathode and the anode, the cathode solution, and the anode and the solution. These values were obtained as a function of the time of the electrolysis. The variation of these differences with time and

What happens during electrolysis of salt water with

2010/3/12HI, I'm new around. My questions is: I have salty water which I perform electrolysis on using copper probes (cathode and anode). One of the copper probes nothing happens to as far as I can see (can't remember which one it is) but the other starts to wear away and

Sciencemadness Discussion Board

Copper metal dissolves as cupric ions (since cuprous are generally unstable, particularly in sulfuric solution), while hydrogen ions are discharged as hydrogen gas. With an inert anode, the sulfuric acid (or sulfate ion if using a reasonably alkaline salt) is oxidized to persulfuric acid (S2O8(2-)

Electrogravimetric determination of copper
