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

1. How does the flow of electric current affect the chemical reactions in a solution?
Ans. The flow of electric current in a solution causes chemical reactions to occur at the electrodes, leading to the formation of new substances through processes like electrolysis.
2. What are some common examples of chemical effects of electric current in everyday life?
Ans. Some common examples include electroplating of metals, electrolysis of water to produce hydrogen and oxygen, and electroplating of jewelry and coins.
3. How does the conductivity of a solution impact the chemical effects of electric current?
Ans. Solutions with higher conductivity allow for better flow of electric current, resulting in more pronounced chemical effects such as faster electrolysis or electroplating.
4. Can the chemical effects of electric current be used for industrial applications?
Ans. Yes, the chemical effects of electric current are utilized in various industrial processes such as electroplating, purification of metals, and production of chemicals like chlorine and sodium hydroxide.
5. How do different factors like current strength and electrode materials influence the chemical effects of electric current?
Ans. Factors like current strength, electrode materials, and concentration of the solution can impact the rate and nature of chemical reactions taking place due to the flow of electric current.
