What is produced at the positive electrode for the electrolysis of copper sulfate?
Oxygen will because the sulfate ions are stable so they will stay in the solution.
When copper is purified by electrolysis which electrode do you think that the pure copper collects at?
cathode
Why does hydrogen gas liberate at Cu electrode in Zn-Cu cell?
In a zinc-copper cell, zinc gives up electrons, forming the negative terminal of the cell, and the electrons flows as electric current through wires. When the electrons reach the other positive terminal, electrolysis of the electrolyte takes place at the positive terminal. Hydrogen ions and the cation of the electrolyte will be attracted to the positive Copper electrode. The hydrogen ions, being less reactive than the cation ions, will take up the electrons on the copper electrode, forming hydrogen gas.
Why does the most dilute solution deposit more copper in electrolysis?
An electrolysis process is based upon movement and flow of ions. More is the solution dilute, more is the movement of ions and more is the conductance of solution. Thus, when the solution is dilute more copper ions flow to the electrode and get deposited there
Reduction occurs at which electrode?
The electrode that removes ions from solution

Copper from impure copper has to be transferred to the pure copper which one has to be connected to the positive terminal?
If it is electrolysis you are talking about, I'm fairly confident the impure copper has to be connected to the positive terminal.
How is copper plated?
To copper-plate another metal, the procedure is pretty simple. You need a DC power source, a bath of copper sulphate, and a copper electrode. Connect the positive terminal of the battery to the copper electrode, and the negative to the item to be plated. When the copper electrode and the item are placed in the copper sulphate solution, the circuit is complete and copper electrons will stick to the item.

What is copper chloride split into by electrolysis?
copper + Chlorine = copper chloride
Why does in a potato when connected to a circuit appears blue near the positive terminal?
copper salts are forming on that electrode and diffusing into the potato flesh.
How can copper be separated from solution of copper compounds?
Usually in a school experiment, you put copper solution into glass. Then you add Positively and negatively charged sticks which are connected with each other and plugged into electricity, which makes pure copper form on the negatively charged stick.
How you prepare copper sulfate?
By electrolysis
