In theMy textbook, it says “Among K+K+, Na+Na+ and Cl--, K+contributeK+ contributes to the resting membrane potential the most, because it has the greatest permeability across the membrane” imembrane.”

I agree with this, but I’m just curious: why is the equilibrium potential of Cl-- (-75mV) closer to the resting membrane potential (-70mV) than that of K+K+ (-90mV)?
