Question

When using an ion selective electrode, why does plotting Measured electric potential vs LogK+ conform to the

nernst equation?

nernst E=Ec+59.16mV (Logak)

3. Discuss why a plot of E vs log [K ] from Part I conforms to equation I (from your jal
manual), and a plot of E vs log ak is not necessary. (10 pts)

The ion-selective electrodes respond to the activity of the specific ion according to the Nernst
equation, which for the K* selective electrode is:
E = E. +2.3
