Question #365

A KCl solution of unknown concentration was placed on the test side of the artifical membrane shown in the Figure. The KCl concentration on the reference side was 80mM. A potential difference of 0 mV was recorded. What was the concentration of the KCl solution on the test side?





When the concentration of KCl on the test side is the same as that on the reference side, the equilibrium potential difference across the membrane will naturally be zero.
