WebDec 1, 1993 · Note that as the potential window shifts as pH changes, conducting the optimisation in synthetic seawater of a typical and average pH results in a potential … WebThe liquid junction potential of the pH cell is sensitive to ionic strength and to the composition of the solution it is in, so moving the electrodes from these low ionic strength buffers to the higher ionic strength of seawater (0.72 mol kg –1) makes apparent pH readings drift for a period of time. Furthermore, different electrode designs ...
