What is the difference between dilute and concentrated solution in electrolysis?

What is the difference between dilute and concentrated solution in electrolysis?

For example, if you have a concentrated solution of sodium chloride, you will get mainly chlorine at the anode. With more and more dilute solutions, you will get less chlorine and more oxygen. Very, very dilute solutions will give mainly oxygen.

What happens when dilute NaCl solution is Electrolysed?

Electrolysis of aqueous sodium chlorideElectrolysis of aqueous NaCl results in hydrogen and chloride gas. At the cathode (C), water is reduced to hydroxide and hydrogen gas. The net process is the electrolysis of an aqueous solution of NaCl into industrially useful products sodium hydroxide (NaOH) and chlorine gas.

Why does molten NaCl undergo electrolysis while solid NaCl does not?

In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.

What is the difference between molten and aqueous NaCl?

In molten sodium chloride, the only available ions are Na+ and Cl−. With electrolysis, the products will be sodium metal and chlorine gas. In an aqueous solution, the sodium chloride still moves the charges from one electrode to the other, but the potential for electrolysis of water is less than Na+ or Cl−.

Why different products are obtained from electrolysis of molten NaCl and electrolysis of a dilute aqueous solution of NaCl?

Electrolysis of aqueous sodium chloride yields hydrogen and chlorine, with aqueous sodium hydroxide remaining in solution. The reason for the difference is that the reduction of Na+ (E° = –2.7 v) is energetically more difficult than the reduction of water (–1.23 v).

Which substance is not produced during the electrolysis of concentrated aqueous sodium chloride?

Electrolysis of Aqueous NaCl Since water can be both oxidized and reduced, it competes with the dissolved Na+ and Cl– ions. Rather than producing sodium, hydrogen is produced.

What is the difference between NaCl and NaCl?

Technically salt can be any ionic compound formed by reacting an acid and a base, but most of the time the word is used to refer to table salt, which is sodium chloride or NaCl. So, you know salt contains sodium, but the two chemicals aren’t the same thing.

What products are formed from the electrolysis of dilute sodium chloride solution?

The product of electrolysis of concentrated aqueous sodium chloride are sodium hydroxide, hydrogen gas and chlorine gas.

How do you separate NaCl from NA?

To extract Sodium metal from NaCl, you must use electrolysis. Electrolysis involves passing electric current through a molten chemical or a chemical in a liquid state. Current travels from the anode to the cathode, separating Sodium from Chlorine.
