Experimental realization of a reference potential for potentiometric measurements in non-ideal media is discussed. A liquid junction-free reference potential is realized at a dropping mercury electrode, using the standard potential of the metallocene redox couple. This approach is particularly suitable for determination of acidity functions that are seamlessly anchored to aqueous standard buffers.
