Standard Cell Potential Calculator
Use standard reduction potentials (E°) from tables.
🔋 What is a Standard Cell Potential Calculator? 🔬
The Standard Cell Potential Calculator is a free, online electrochemistry tool designed to calculate the standard electrode potential (E°cell) of an electrochemical cell under standard conditions (1 M concentration, 1 atm pressure, 298 K temperature). This calculator applies the fundamental electrochemical equation:
E°cell = E°cathode − E°anode
Using scientifically validated standard reduction potentials, the tool delivers fast, accurate, and error-free results, making it indispensable for chemistry students, educators, researchers, and competitive exam aspirants (IIT-JEE, NEET, CUET, CSIR-NET).
⚡ It eliminates manual calculation errors
⚡ Saves time during problem solving
⚡ Enhances conceptual clarity in redox reactions
🌍 Applications of Standard Cell Potential in Daily Life
