NCERT Exemplar Class 8 Science Chapter 14: Chemical Effects of Electric Current
NCERT Exemplar Solutions for Class 8 Science Chapter 14 – Chemical Effects of Electric Current introduces the relationship between electricity and chemical changes. Students first learn to test whether a substance conducts electricity, using simple experiments with solutions like lemon juice and salt water.
The chapter explains the concept of electrolysis, where an electric current passes through a liquid and causes chemical changes. Subtopics include electroplating, which is widely used in industries to coat objects with metals like gold, silver, or chromium. NCERT Solutions for Class 8 Science also highlight the role of current in the purification of metals and its use in manufacturing. The importance of conductors, insulators, and electrodes is discussed in detail. By practicing NCERT Exemplar Solutions for Class 8 Science Chapter 14, students develop a deeper understanding of applied chemistry and its industrial applications.
