FAQs on Chemical Effects of Electric Current NCERT Solutions - Class 8 Science
1. What does this Chapter Summarise Students About?
In this chapter, students will learn that specific liquids are excellent conductors of electricity while some aren’t. Additionally, most liquids that do conduct electricity are mixtures of acids, bases, and salts. Along with this, you will understand that the path of an electric current through conducting liquid produces chemical effects. Lastly, you’ll learn about electroplating- it is the methodology of depositing a layer of any respective metal on another object through electricity.

The study material offered by Vedantu will help students create a strong foundation for their academics, thereby helping them learn how they can use knowledge about what they’ve learned so far correctly. Additionally, students will also learn distinguishing skills to get clarity on concepts like electroplating.
3. What are the three chemical effects of electric current?
Chemical effects of electric current include permanent changes that cannot be reversed. Upon passing current through a solution, gases may be evolved at electrodes. Deposits of metal may also be seen along with a change in the colour of the solution. These are the three main chemical effects of electric current. You can refer to Vedantu Class 8 NCERT Chapter 14 Solutions to get more clarity on the topic.
4. What is the chemical effect of electricity? Give some examples of chemical effects?
Chemical effects of electricity are seen when an electric current is passed through a conducting liquid solution. The changes seen are permanent and irreversible. Gas evolution at anodes and cathodes, visual changes like a shift in the colour of the solution and deposition of metal are also seen. These are all examples of the various chemical effects of electricity.
5. What is Electroplating?
Electroplating is one of the real-time applications of the chemical effects of electricity. It is a process in which a layer of a desirable metal is deposited atop another material. The deposited metal generally has some attributes that the original metal lacks and could benefit from. For example, chromium plating is done on many household objects such as bath taps and kitchen gas burners. This is simply because chromium does not corrode and resists scratches.
6. Why is iron coated with zinc?
The process of coating iron with a layer of zinc is termed galvanization. Iron is used for construction purposes because it is a very sturdy and strong metal. However, iron tends to corrode and rusts on exposure to air and moisture due to the formation of hydrated ferric oxide. This is why a coating of zinc is deposited on iron to protect it from corrosion and inhibit the formation of rust.
7. What are good and bad conductors?
Some materials allow for the passage of electricity quite easily while other materials resist its flow. It is recommended to classify materials as good conductors and poor conductors instead of classifying them as insulators and conductors as most materials can conduct under certain conditions.
