What happens when electric current is passed through water containing a few drops of an acid?

What happens when electric current is passed through water containing a few drops of an acid?

Add a few drops of dilute sulphuric acid to water to make it more conducting. If electric current is passed through acidified water, then bubbles of Oxygen gas and hydrogen gas are produced at the two electrodes in immersed in it.

What happens when we pass electric current in 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.

Why are few drops of H2SO4 added to water?

When acid is added to water, the strong bonds of acid are broken and they dissociate in to ions, thus releasing a large amount of energy in the form of heat and thus we need to add few drops or else there would be generation of large amounts of heat and may result in burns.

Why are few drops of acid added to water during electrolysis?

To carry out electrolysis in water,a few drops of sulphuric acid is added to the water. It is because pure water is a bad conductor of electricity. So it would not conduct electricity. So the acidulated water becomes conductig and hence electricity is conducted.

When an electric current is passed through water what is formed on the electrodes?

Question 4: What happens when electrodes are immersed in water and current is passed through them? Answer: When electrodes are immersed in water and current was passed through water; bubbles of oxygen and hydrogen are produced. Oxygen bubbles are formed at the electrode connected to the positive terminal.

When electric current passes through a solution effect is produced?

explanation:When an electric current passes through a solution, the solution decomposes into its positive and negative ions. This process of decomposition of the solution is a chemical effect.

How does electricity flow through water?

In order to get electricity to flow through water, you have to give the electrons so much energy that they physically break the water molecules – this process creates ions (charged parts of water molecules, in this case) that can then flow through the water to the other side of the container (where the energy state is …

Why we add Dil H2SO4 in electrolysis of water?

Because adding dilute sulphuric acid makes it slightly acidic, that mesns the water gets impure and thus electricity flows through it easily. In other words, adding sulphuric acid makes water more conductive thus making current flow through it.

Which acid is used in electrolysis of water?

sulphuric acid
The electrolyte is dilute sulphuric acid (= acidified water) which, during electrolysis is split into hydrogen and oxygen gases.
