Which products are obtained when an electric current is passed through sodium chloride solution?

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 are the products of electrolysis of aqueous sodium chloride?

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

When electricity is passed through the aqueous solution of sodium chloride?

Explanation : When electricity is passed through an aqueous solution of sodium chloride, it gives hydrogen, chlorine and sodium hydroxide as a product. The balanced chemical equation is, This process is called as Electrolysis of Brine.

IT\'S FUNNING:  Do solar panels increase your property taxes?

What are the products of sodium chloride?

Large quantities of sodium chloride are also used in industrial manufacturing settings to help make a range of products, from plastic, paper, rubber and glass, to chlorine, polyester, household bleach, soaps, detergents and dyes.

Why are different products obtained when molten and aqueous NaCl is electrolyzed?

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−.

How is sodium obtained from sodium chloride?

By electrolysis, common salt, sodium chloride, NaCl, can be broken down into its elements, sodium and chlorine. … To obtain sodium by electrolysis, we will first melt some sodium chloride by heating it above its melting point of 1,474°F (801°C).

Which three chemical substances are obtained when electricity is passed through an aqueous solution of brine write one industrial use of each?

When electricity is passed through a concentrated solution of sodium chloride (called brine), it decomposes to form sodium hydroxide, chlorine, and hydrogen gas. (i) Use of Sodium hydroxide (NaOH). It is used for making soaps and detergents. (ii) Use of Chlorine (Cl2).

When electricity is passed through an aqueous solution of sodium chloride name the products obtained and also their location What is this process called?

When electricity is passed through an aqueous solution of sodium chloride, the three products are obtained which is hydrogen, chlorine and sodium hydroxide. But this process is called chlor-alkali process because here, chlor stands for chlorine and alkali for sodium hydroxide.

IT\'S FUNNING:  Frequent question: Which continent has the most potential for solar power?

When an electric current is passed through an aqueous solution?

When an electric current is passed through an aqueous solution of sodium chloride, sodium ions move towards cathode and chloride ions move towards anode.

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

When electricity is passed through brine it decomposes to form sodium hydroxide along with the evolution of chlorine gas at anode and hydrogen gas at cathode.

What are the reactants and products of sodium chloride?

burning sodium metal in chlorine gas to form sodium chloride is what type of reaction. It is a combining reaction. Two reactants combine together to produce one product. Sodium and chlorine are the two reactants and sodium chloride is the only product.

What happens during electrolysis of sodium chloride?

As shown above, the electrolysis of sodium chloride solution will produce chlorine gas at the anode and hydrogen gas at the cathode. During the electrolysis, hydrogen and chloride ions are removed from solution whereas sodium and hydroxide ions are left behind in solution.

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.

What product is formed at the anode when molten sodium chloride NaCl is electrolyzed using a Downs cell?

Electrolysis of Molten Sodium Chloride

Molten (liquid) sodium chloride can be electrolyzed to produce sodium metal and chlorine gas. The electrolytic cell used in the process is called a Down’s cell (see figure below). Figure 23.10.

IT\'S FUNNING:  What are two sources of mechanical energy?

Which product is obtained at anode on electrolysis of aqueous solution of sodium acetate?

Sodium acetate on Kolbe’s electrolysis gives ethane. It is formed at anode.
