The chapter Electrochemistry in UP Board Class 12 Chemistry deals with chemical reactions involving the flow of electric current and the movement of ions in solutions. Students learn the basics of electrolytes, types of electrolytes (strong and weak), and ionic conductivity, which are crucial for understanding the behavior of solutions under electric current.
Key topics include electrolysis, Faraday’s laws of electrolysis, and the quantitative relationship between electric charge and chemical change, along with numerical applications. The chapter also explains electrochemical cells, including galvanic (voltaic) cells, their electromotive force (emf), and standard electrode potentials.
Students study Nernst equation, which helps calculate cell potential under non-standard conditions, and learn about fuel cells, corrosion, and their practical applications in daily life and industries. Numerical problems, derivations, and experiments make the chapter highly practical and relevant for board exams and competitive exams like NEET and JEE.
This chapter builds a strong foundation in physical chemistry and practical applications of electricity in chemical systems.
