What chemical reaction takes place when electricity passes through water?

Electrolysis of water is a decomposition reaction ; a single reactant breaks down into more than one product. The breaking down of H 2 O into H 2 and O 2 by passing electricity is known as electrolysis of water.

What happens when electricity is passed through water?

When an electric current is passed through water, “Electrolysis of water” occurs, which is the decomposition of water (H2O) into hydrogen gas (H2) and oxygen (O2). … Hydrogen gas forms at the cathode where the electrons enter the water and at the anode, oxygen is formed.

What type of chemical reactions take place when electricity is passed through water * 1 point displacement combination decomposition double displacement?

What type of chemical reactions take place when electricity is passed through water? Explanation: Electrolysis of water is a decomposition reaction.

When electricity is passed through water does it contain acid?

Answer: During the process of electrolysis of water, dilute sulphuric acid splits into when electricity is passed through the dilute sulfuric acid solution. The electrolyte is dilute sulfuric acid (= acidified water) which, during electrolysis is split into hydrogen and oxygen gases.

What type of chemical reactions takes place when?

Explanation: it is a combination reaction or oxidation reaction. Answer : The chemical reaction which takes place when Magnesium wire is burnt in air is Combination Reaction. Another type of reaction also takes place which is called Exothermic Reaction because heat or energy gets released when it is burnt in air.

What type of reaction is Pb CuCl2?

The correct answer is displacement. Pb + CuCl2 → PbCl2 + Cu. The given reaction is an example of a displacement reaction. A reaction in which one element is replaced by another element of the compound is known as displacement reaction.

What type of chemical reaction takes place when electricity is passed through Aluminium oxide?

This is a decomposition reaction.

What type of chemical reactions take place when electricity is passed through 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.

What type of chemical reaction takes place when digestion of food occurs in the body?

Digestion of food in our body is a decomposition reaction.

What type of chemical reaction takes place when limestone is heated?

When limestone is heated in a kiln, the calcium carbonate breaks down into calcium oxide and carbon dioxide. This type of reaction is called thermal decomposition. The process is called calcining.

Why is H2SO4 used in electrolysis of water?

Why ? Water is a poor conductor of electrcity. Addition of a few drops of sulphuric acid (H2SO4) makes water conducting in nature because the acid ionises in water to release H+ ions and HSO-4 ions.

Which acid is used in electrolysis of water?

The electrodes must be made of an inert wire. Students should note that the electrolysis will only take place when electricity is passed through the dilute sulfuric acid solution. The electrolyte is dilute sulfuric acid (= acidified water) which, during electrolysis is split into hydrogen and oxygen gases.

Why is dilute sulphuric acid used in electrolysis of water?

A diluted form of sulphuric acid is called acidic water. Sulphuric acid is added to water in order to increase the number of ions. Therefore, the electrolysis of dilute sulphuric acid is also called the electrolysis of acidic water.
