Which elements would you get when electricity is passed through molten lead bromide?
Lead and bromine
Why does electrolysis not occur unless lead II bromide is molten?
Because it has to be an ionic substance, either by being molten or by being in solution.
How could lead bromide be made into a liquid for electrolysis?
by changing it into a molten state I would guess
Is lead bromide a metallic bond?
Lead bromide has an ionic bond.
Is lead bromide soluble in water?
Lead Bromide's solubility in water is extremely low. 0.8g of Lead Bromide dissolves in 100g of water at 20°C.
What is produced at the positive electrode of the electrolysis of molten lead bromide?
Lead in solid state

Lead and bromine

Does sodium Bromide conduct electricity in liquid state?
after heating Lead Bromide, it becomes a molten which conducts electricity. so the answer is yes it does. lead bromide's an ionic bond. so, compared to the structure of an ionic bond, lead bromide does conduct electricity when molten. When molten or in an aqueous state, the ions become free to move and so it can carry electric charge around as well.
What is the name of the compound PbBr4?
It's Lead (IV)Bromide We use roman numerals when it's a transition metal + nonmetal
What does lead nitrate and potassium bromide make?
lead nitrate + potassium bromide --> lead bromide + potassium nitrate
Is lead bromide a metallic bond?
Lead bromide has an ionic bond.
Is lead bromide soluble in water?
Lead Bromide's solubility in water is extremely low. 0.8g of Lead Bromide dissolves in 100g of water at 20°C.
What is the product Mixing lead nitrate and potassium bromide?
It is lead bromide and potassium nitrate
Why must lead bromide must be molten for electrolysis to take place?
Because it is a solid and the ions aren't free to move otherwise, i'm lead to believe it is due to that anyway, I would seek a second opinion
Why does solid lead bromide not allow the passage of electricity?
Lead(II) bromide is used because it melts at an unusually low temperature for an ionic compound (373 °C). Lead can be fairly safely handled afterwards (taking care to ensure that hands are washed after any contact with the metal). Bromine is a coloured acidic gas with a characteristic smell. Electrolysis is not possible with solid lead(II) bromide. This is because the ions are held in a three-dimensional lattice, unable to move freely to the electrodes. Melting enables the ions to become mobile and to travel to the respective electrodes. At the cathode (-) molten lead is formed: Pb2+(l) + 2e- → Pb(l) At the anode, gaseous bromine is evolved: 2Br-(l) → Br2(g) + 2e-
