Why is hydrogen collected at cathode instead of sodium during the electrolysis of sodium chloride?
Wiki User
∙ 12y ago
When an aqueous solution of sodium hydroxide is electrolyzed, hydrogen is produced at the cathode because hydrogen can be produced at a lower voltage than can sodium, and the supply of hydrogen from the water of the solution is sufficient to consume all the current supplied. When molten sodium chloride is electrolyzed, however, sodium is produced at the cathode.

Can you separate hydrogen in the sodium chloride solution?
NaCl itself will not render any hydrogen, however you can separate hydrogen from the water through the process of electrolysis. During electrolysis of NaCl solution, hydrogen will be evolved at cathode.
Electrolysis of lithium chloride at the cathode?
lithium
How do you get hydrogen from water?
Electrolysis of water gives off Hydrogen at the cathode (-ve chrged terminal).
What will happen when electrolysis of dilute sodium chloride solution using copper and zinc electrode?
Usually hydrogen will evolve from the cathode and oxygen from the anode, but if zinc is the anode, it may dissolve to produce zinc ions in the solution either instead of or along with oxygen evolving.
How do you use electrolysis in a sentence?
Then use electrolysis to transfer all the copper from the impure anode to the cathode.

Electrolysis of lithium chloride at the cathode?

In electrolysis of dilute silver chloride what is discharged at the cathode?
I think the cathode will be coated in silver.
How do you get hydrogen from water?
Electrolysis of water gives off Hydrogen at the cathode (-ve chrged terminal).
What is electrolysis of aqueous sodium chloride?
Sodium metal can be obtained by electrolysis from molten mixture of sodium chloride and calcium chloride in Down's cell. The metal can not be obtained by electrolysis from aqueous solution, because hydrogen will evolve instead.
What is chemical equation to turn water to fuel?
Electrolysis of water produces hydrogen and oxygen gases at different electrodes. 2H2O(l) --> 2H2(g) + O2(g) Hydrogen is collected at the cathode (-pole). Oxygen is collected at the anode (+pole).
What will be the products on cathode and anode during electrolysis of the solution of magnesium sulphate?
Cathode - Hydrogen Anode - Oxygen
Why electrolysis does not happen in solid sodium chloride?
when an aqueous solution is used, hydrogen gas is evolved at cathode, instead of depositing sodium metal.
What materials are made in electrolysis?
This depends on what you are electrolyzing. Water, the most common electrolyte, (the material being electrolyzed) separates into Hydrogen molecules on the cathode and Oxygen molecules at the anode. These gasses will bubble up to the top of the electrolysis chamber where they can be collected.
How will you separate a mixture of hydrogen and chlorine?
When gaseous hydrogen and gaseous chlorine are mixed each other, they react vigorously to form hydrogen chloride (HCl). The only way to separate elements from the gas HCl is electrolysis where chlorine is discharged at cathode and the other at anode.
What would be formed at the cathode and the anode during the electrolysis of sodium hydroxide solution?
Hydrogen gas would evolve from the cathode and oxygen gas would evolve from the anode.
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.
