chemical effects of electric current

Front

What is the chemical effect of electric current?

Back

The chemical effect of electric current refers to the changes that occur in a substance when an electric current passes through it, often resulting in chemical reactions.

Front

Which materials are considered conductors of electricity?

Back

Materials that allow electric current to flow through them easily, such as metals (like copper and aluminum), salt water, and lime juice.

Front

What is electrolysis?

Back

Electrolysis is a chemical process that uses electric current to drive a non-spontaneous chemical reaction, often used to decompose compounds.

Front

What is formed at the cathode during electrolysis of copper sulphate solution?

Back

Copper is formed at the cathode during the electrolysis of copper sulphate solution.

Front

What is the role of the anode in electrolysis?

Back

The anode is the electrode where oxidation occurs, and it attracts anions (negatively charged ions).

Front

What is the role of the cathode in electrolysis?

Back

The cathode is the electrode where reduction occurs, and it attracts cations (positively charged ions).

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows electric current to flow through it easily, while an insulator resists the flow of electric current.

Front

What happens to water when an electric current passes through it?

Back

Water undergoes electrolysis, breaking down into hydrogen and oxygen gases.

Front

What is the significance of the charge of particles in electric current?

Back

Electric current is the flow of charged particles, which can be either positive (like protons) or negative (like electrons), depending on the material.

Front

What is an example of a non-conductor of electricity?

Back

Petrol is an example of a non-conductor of electricity.
