What process occurs at the anode in the electrolysis of molten Sodium chloride?
oxidation
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
How can cadmium be obtained in its pure form?
By electrolysis of a solution or molten salt containing cadmium ions. Under properly controlled conditions, this will result in deposition of pure cadmium at the cathode.
What is the metal ore for sodium?
Rock salt. Sodium is then extracted by molten salt electrolysis, which also produces large amounts of chlorine gas. Table salt could also be used but rock salt is cheaper.
Molten sodium iodide?
cell emf for electrolysis of molten lead (II) iodide
What happens at the negative electrode during the electrolysis of molten aluminium?
Al3+ + 3e- --> Al(metal)
What is formed at the anode and the cathode during the electrolysis of sodium iodide?
If a solution of NaI is electrolyzed, iodine is formed at the anode and hydrogen gas at the cathode. In the instance if it is the molten liquid of NaI, it would emit sodium from the sodium at the cathode and iodine at the anode.
What is the electrolysis of sodium chloride?
1. The products of the molten sodium chloride electrolysis are sodium and chlorine. 2. The products of the water solution of sodium chloride electrolysis are sodium hydroxide and hydrogen.
How do they get potassium?
By electrolysis of Molten Potassium chloride
What happens when molten salts is electrolysed?
Electrolysis of molten sodium chloride: yield sodium and chlorine.Electrolysis of sodium chloride water solution: yield hydrogen, sodium hydroxide and chlorine.
Why do you use molten NaCl in electrolysis instead of an aqueous solution of NaCl?
Molten salt electrolysis is used to obtain sodium and chlorine. Electrolysis of the water solution is used to obtain sodium hydroxide and hydrogen.
What is the structure of molten sodium chloride?
In molten sodium chloride the free moving particles are Na+ and Cl- ions, during electrolysis sodium ion moves towards cathode and chloride ion towards anode.
When a substance is decomposed by an electric current what type of reaction does it have?
This is electrolysis of a molten compound.
Where does chlorine form in an electrolytic cell during the electrolysis of molten Na Cl?
Chlorine is released as a gas (diatomic molecule Cl2).
What chemicals can be obtained from the electrolysis of sodium chloride?
Electrolysis of a water solution: sodium hydroxide, hydrogen, chlorine..Electrolysis of molten NaCl: sodium, chlorine.
Explain why a substance needs to be either in a solution or molten for electrolysis to work?
Because electrolysis needs a liquid to conduct the electricity.
