. Give two reasons why graphite (carbon) electrodes are used in electrolysis.
5. You have 2 compounds called X and Y.
X melts at 1200 degrees C and is soluble in water.
Y melts at 156 degrees C and is insoluble in water.
Draw 2 diagrams to show how you could prove which of these substances is an electrolyte or a non- electrolyte.
How would you know which was an electrolyte and which was not.
What must a substance contain to be an electrolyte?
