FAQs on PPT: Chemical Effects of Electric Current - Science Class 8

1. What are the chemical effects of electric current?
Ans. The chemical effects of electric current include electrolysis, where a chemical reaction is caused by passing an electric current through a solution containing ions.
2. How does electric current affect the pH of a solution?
Ans. When an electric current passes through a solution, it can cause the pH of the solution to change by producing acidic or basic substances through electrolysis.
3. Can electric current be used to plate one metal onto another?
Ans. Yes, electric current can be used in electroplating processes where a metal is deposited onto the surface of another metal through the use of an electric current.
4. What is the role of electrodes in chemical effects of electric current?
Ans. Electrodes are used to conduct electricity into and out of a solution during electrolysis. They play a crucial role in facilitating the chemical reactions that occur.
5. How does the amount of current affect the chemical reactions in electrolysis?
Ans. The amount of current passing through a solution during electrolysis can affect the rate of chemical reactions. Higher currents can speed up the reactions, while lower currents may slow them down.
