Electrochemistry Important Questions for NEET Overview 

Electrochemistry holds significant weightage in the NEET syllabus. It involves the study of redox reactions, electrochemical cells, and the practical applications of electric current in chemical transformations. Mastering this topic not only boosts your NEET score but also lays a strong foundation for future studies in medical and engineering fields.

What is Electrochemistry?

Electrochemistry is the branch of chemistry that studies the relationship between electricity and chemical reactions. It focuses on the movement of electrons in redox reactions, which occur in batteries, electroplating, and corrosion processes. Key concepts include the Nernst equation, electrolysis, conductance, and galvanic cells.

1. Doubles
2. Reduces to half
3. Remains same
4. Becomes zero

Q7 Consider the following four electrodes:

P = Cu²⁺ (0.0001 M) | Cu(s)
