1. By comparing the potentials of four kinds of 3.5 n. KCl-calomel electrode, it was found that the potential attained a constant value in a short time, at the latest in 2 days after fresh preparation, if the KCl-solution for the electrode had been thoroughly saturated with HgCl before its preparation.
2. Single electrode potentials of 3.5 n. KCl-calomel electrode (π3.5) at several temperatures were investigated and the following data were found.
_??_ These values lie approximately on two lines expressed by the two following forumulae.
π3.5=0.28382t-0.03988 (13°-25°)
π3.5=30249t-0.05967 (25°-43°)
