Answer:
A.. because its ions are fixed in the crystal lattice.
B. Lead bromide is an ionic compound and can conduct electricity when the ions are free to move - either molten or in aqueous solution. ... Electricity flow and therefore electrolysis can only occur when the ions are free to move.
D. lead in the heated liquid state) ..
E. The main electrolytes include sodium, chloride, potassium, calcium and magnesium.
F. Graphite rods are used as electrodes in electrolysis because graphite's structure enables it to be an excellent conductor
