What is the product of the electrolysis of dilute NaCl?

The net process is the electrolysis of an aqueous solution of NaCl into industrially useful products sodium hydroxide (NaOH) and chlorine gas.

What are the products of electrolysis of molten NaCl at cathode and anode?

In the electrolysis of molten NaCl, sodium is deposited at the cathode while chlorine gas is liberated at anode. Where as in the electrolysis of aqueous solution of NaCl, Cl2 gas is liberated at anode and H2 gas is liberated at cathode.

When NaCl solution is Electrolysed what has formed at the anode?

chlorine gas
When an electric current is passed through concentrated sodium chloride solution, hydrogen gas forms at the negative electrode , chlorine gas forms at the positive electrode, and a solution of sodium hydroxide also forms.

What is produced at the anode in electrolysis of solutions?

At the anode Oxygen is produced (from hydroxide ions), unless halide ions (chloride, bromide or iodide ions) are present. In that case, the negatively charged halide ions lose electrons and form the corresponding halogen (chlorine, bromine or iodine).

How is the electrolysis of aqueous NaCl different from molten NaCl?

Electrolysis of molten NaCl decomposes this compound into its elements. Electrolysis of aqueous NaCl solutions gives a mixture of hydrogen and chlorine gas and an aqueous sodium hydroxide solution.

What are the products of electrolysis at cathode and anode when NaCl solution is electrolysed using Cu electrodes?

Electrolysis of aqueous sodium chlorideElectrolysis of aqueous NaCl results in hydrogen and chloride gas. At the anode (A), chloride (Cl-) is oxidized to chlorine.

Why is electrolysis of dilute NaCl different from concentrated NaCl?

During the electrolysis of dilute NaCl solution, Na+, Cl- and water are present. When concentrated NaCl solution undergoes electrolysis, sodium hydroxide and hydrogen are produced at the cathode while chlorine is produced at the anode.

What is the anode in electrolysis of brine?

Explanation. In the industrial of brine carbon is the anode while mercury is the cathode.

What is the anode made of in the electrolysis of brine?

Because sodium and potassium are reactive metals, you will get hydrogen ions discharged at the negative cathode giving hydrogen gas. Sodium bromide gives hydrogen at the cathode and the element bromine at the anode – you would see a orange-brown colouration appearing around the positive electrode.
