NCERT Grade 8 Science Chapter 14, Chemical Effects of Electric Current deals with the conduction electric current in liquids. In Class VI, students made a tester to test whether a particular material allows the electric current to pass through it or not with the help of an activity. It was found that metals such as copper and aluminium conduct electricity whereas materials such as rubber, plastic and wood do not conduct electricity. However, so far the tester was used or to test materials which were in solid state. But what about liquids? Do liquids also conduct electricity? This chapter provides the solutions to these questions.
A very interesting chapter, it evolves the curiosity amongst students with the help of simple activities to prove that when electricity conducting liquids are used; electricity can be conducted.The chapter deals with the chemical effects of electric current on objects and its applications.Electroplating – a great invention by man is an application of chemical effects of electric current that is used widely.
