Calculate the membrane potential caused by the different concentrations of an ionic element on either side of the membrane. Assume all ions are singly charged (z = 1). The concentration outside is 11 and that inside is 150 Give your answer in milliVolts (mV). Make sure you include the sign. The temperature T is 300k. You will need to look up the values of Boltmann's constant kB and the charge on the electron.

Potentiometric Titrations

Potentiometric titration is one of the important titration methods and is mainly carried out to characterize acid solutions. It follows a method similar to that of the normal titration technique, but the main difference is that there is no indicator used in the potentiometric titrations. Instead of using an indicator, electrodes are employed for monitoring the whole titration process. A scientist named Robert Behrend did the potentiometric titration for the first time, and it was done using the mercurous solution and potassium chloride.
