electrolysis

Question 1

solid ionic compounds cannot

Answer 1

conduct electricity as the ions are locked in place and are not free to move, the ions are held by strong electrostatic forces of attraction

Question 2

when an ionic compound is melted or dissolved in water

Answer 2

the forces of attraction are broken and the ions are free to move, these liquids and solutions can now conduct electricity (electrolytes)

Question 3

2 electrodes in electroloyis

negative is the

positive is the

Answer 3

a) cathode - covered with electrons (anions come here)

b) anode - lack of electrons (cations come here, negative ions)

Question 4

cathode is where ____happens

anode is where _____ happehs

Answer 4

oxidation

reduction

Question 5

what happens at the cathode if the metal is more reactive than hydrogen?

Answer 5

hydrogen is produced

Question 6

what if the metals less reactive then hydrogen then what?

Answer 6

then the metal is discharged at the cathode
