Nernst equation for ph meter

WebSep 25, 2014 · 1 Answer. Ernest Z. · Media Owl. Sep 25, 2014. pH doesn't affect the Nernst equation. But the Nernst equation predicts the cell potential of reactions that depend on pH. If H⁺ is involved in the cell reaction, then the value of E will depend on the pH. For the half-reaction, 2H⁺ + 2e⁻ → H₂, E∘ = 0. According to the Nernst equation, WebThe temperature dependency of the Nernst equation is easily calculated, and as a rule, only this temperature influence is considered by instrument manufacturers when they incorporate conventional manual or automatic temperature compensation in their …
