Electrolysis

Question 1

Define the terms:
Electrolysis
Cations
Anions
Electrolyte

Answer 1

Electrolysis: break down of an electrolyte using electricity
Electrolyte:the liquid being used in electrolysis
Cation:positive ion attracted to the cathode
Anion:negative ion attracted to the anode

Question 2

Define
Cathode
Anode

Answer 2

Cathode:negative electrode
Anode:positive electrode

Question 3

What does PANIC stand for?

Answer 3

P ositive
a node
N egative
I s
C athode

Question 4

What are the charges on cations and anions

Answer 4

Cations:positive
Anion:negative

Question 5

How do cations and anions form?

Answer 5

Cations form when atoms lose electrons so they have more protons than electrons

Anions form when an atom gains electrons and so they have more electrons than protons

Question 6

What does OIL RIG stand for?

Answer 6

Oxidation
Is
Loss of electrons
Reduction
Is
Gain of electrons

Question 7

Why don’t simple covalent molecules conduct electricity?

Answer 7

Don’t contain free electrons or ions

Question 8

Why don’t solid ionic compounds conduct electricity?

Answer 8

The ions or electrons are in fixed place so they can’t move

Question 9

In what forms can ionic compounds conduct electricity?why?

Answer 9

When molten:electrons are able to move freely and so carry current
When dissolved in water:ions are separate and are free to move in solution and so can carry a current
