You asked: What happens when an electric current is passed through aqueous sodium chloride?

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. … However, sodium is too reactive for this to happen so hydrogen is given off instead.

What happens when electricity is passed through an aqueous solution of NaCl?

When electricity is passed through an aqueous solution of NaCl ( called brine ), it decomposes to form NaOH ( sodium hydroxide), Cl2 and H2. This process is called Chlor – Alkali process due to the substances formed.

When current is passed through a solution of NaCl?

When current is passed through molten NaCl i.e. sodium chloride, it decomposes into sodium and chlorine gas. Both sodium and chlorine gas move towards the electrode opposite to their own charge and either loses an electron or gains one.

When an electric current is passed through an aqueous solution of sodium chloride its pH?

When an electric current is passed through an aqueous solution of sodium chloride. During electrolysis of NaCl(aq),H+ ions are discharged at cathode and the pH of solution increases due to decrease in [H+] .

What happens when electricity is passed through an aqueous solution of sodium chloride write the balanced chemical equation What is this process called mention one important use of each of the product so obtained?

Electrolysis involves the movement of ions to the electrode. Solid-state does not allow the movement of ions and unsuitable for electrolysis. When melted at high temperature, sodium chloride separates into sodium and chloride ions, so that, electrolysis can take place to form sodium atom and chlorine gas.

When electricity is passed through an aqueous solution of sodium chloride three products are obtained then why is the process called?

This is known as chlor – alkali process because when the electricity pass through the aqueous solution then it decompose to form sodium hydroxide. So it is called chlor – alkali process.

When electricity is passed through an aqueous solution of sodium chloride What are the three products?

When electricity is passed through an aqueous solution of sodium chloride, the three products are obtained which is hydrogen, chlorine and sodium hydroxide.

When current is passed through aqueous solution of NaCl which gas is liberated?

Electrolysis of aqueous NaCl solution gives H2 at the cathode and not Na. Cl2 gas is liberated at the anode.

What is brine solution?

Brine, salt water, particularly a highly concentrated water solution of common salt (sodium chloride). Natural brines occur underground, in salt lakes, or as seawater and are commercially important sources of common salt and other salts, such as chlorides and sulfates of magnesium and potassium.

When electricity is passed through an aqueous solution of sodium chloride What is XY and where it will be produced?

Answer: X is Sodium hydroxide. Y is Chlorine gas.

What happen when electricity is passed through water?

When electricity is passed through ordinary water, it decomposes to give hydrogen and oxygen gas. When the two terminals of a battery are combined with negative and positive electrodes that are immersed in water then the water is dissociated into its oxygen and hydrogen components.

What happens at cathode when an electric current is passed through an aqueous solution of an acid?

When electricity is passed through an aqueous solution of an acid, the H+ ions reach the cathode and each H+ ion picks up one electron from the cathode to form H2 gas. Because of this reaction, an aqueous solution of acid conducts electricity.

When current of electricity is passed through water hydrogen ions attracted to electrode?

When electric current is passed through water , it decomposes to give hydrogen gas and oxygen gas. Water splits up into H+ ions and OH- ions . Positive H+ ions will move towards the negative terminal that is cathode and OH- ions will move towards anode.
