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.
