1. In electrolytic cells, the energy conversion is from:
chemical to electrical
chemical to mechanical
electrical to chemical
electrical to mechanical
2. A solution that can conduct an electric current is called:
a concentrated solution
an electrolyte
a dilute solution
electrolysis
3. Study the diagram.Which is the anode?
X, which is negative
X, which is positive
Y, which is negative
Y, which is positive
4. The reaction that occurs at the cathode of an electrolytic cell is:
an oxidation ½ reaction
a reduction ½ reaction
both, an oxidation and a reduction ½ reaction
neither an oxidation or reduction ½ reaction
5. During the electrolysis of concentrated copper chloride, electrons are provided by …………………………
the anode
the cathode
the electrolyte
the cell
6. A piece of copper wire and a copper chloride solution are both good conductors of electrical energy. The carriers of electrical energy in copper and in the copper chloride solution, are respectively:
electrons and ions
ions and electrons
electrons and protons
protons and electrons
7. In the electrolysis of CuCl2 :
copper atoms are formed at the anode
copper ions are reduced
copper ions are oxidised
chlorine is reduced
8. During electrolysis, anions move towards the ……
cathode because the cathode is positive
cathode because the cathode is negative
anode because the anode is positive
anode because the anode is negative
9. In which beaker must water be poured so that the bulb will glow?
in X and in Y
in X only
in Y only
neither X nor Y as the bulb will not glow anyways
10. In an electrolytic cell,:
the anode gets coated by atoms
the anode gets coated by ions
the cathode gets coated by atoms
the cathode gets coated by ions
