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.
What is true of both galvanic and electrolytic?
reduction happens at the cathode Oxidation happens at the anode
What is true of both and electrolytic cells?
reduction happens at the cathode Oxidation happens at the anode
What happens when water moves out of a cell if the cell is placed in a what solution?
Hypotonic Solution
Do components of a solution separate on standing?
No, the components of a solution do not separate on standing. If that happens, then the mixture is heterogeneous and is not a solution.
What happens when electricity is passed through aqueous solution of sodium chloride?
In aqueous solution, H2 is evolved at the cathode (instead of sodium) and chlorine gas is collected at the anode.
What is true of both galvanic and electrolytic cells?
*electrolytic cells Oxidation occurs at the cathode
What happens in the cathode in an electrolytic cell?
Reduction occurs at the cathode in an electrolytic cell.

What happens in the cathode?
Metals ions form solid metal
A voltaic cell is made with gold and sodium electrodes What happens at the cathode of this cell?
Gold is reduced. Gold is plated onto the cathode.
What happens when smaller area is provided to cathode than anode?
When the area provided to the cathode is smaller than the anode the electrons will still flow.
Is sugar in water an electrolyte solution?
No sugar is not an electrolyte- it is not because it does not carry the charges and does not have any electricity in it, it remains whole and does not break down like an electrolyte is supposed to. An example of an electrolyte is salt- an Aquous solution of NaCl (Sodium Chloride).
What happens in a hydrogen oxygen fuel cell?
Oxygen diffuses through the cathode
What happens in a hydrogen-oxygen fuel cell?
Oxygen diffuses through the cathode
