Nernst Equation Calculator

Calculate cell potential under non-standard conditions using E = E° - (RT/nF) ln Q. Find cell potential (E), reaction quotient (Q), temperature (T), or number of electrons (n). Features 20+ common half-reactions (Li⁺/Li -3.04V to F₂/F⁻ 2.87V), common electrochemical cells (Daniell Cell 1.10V, Zn-Ag 1.56V, etc.), temperature units (K, °C), potential units (V, mV), and step-by-step solutions. Perfect for electrochemistry students.
