The stability constants of M(II)Cl_2 (M(II) = Ca, Sr, Ba) in methanol have been determined by C 1^- ion measurements with Ag-AgCl electrodes. All measurements were made at 25.0 ± 0.1℃ and at an ionic strength of about 0.05 M, adjusted with sodium and the respective metal perch1 orates. Since both of the stepwise stability constants, K_1 for monochloride and K_2 for dichloride, were relatively small, the K_2 values could not be determined with this measurements at a low ionic strength whereas the K-^ values were obtained with somewhat larger errors. It is interesting that the order of magnitude in Kj is Sr > Ba-Ca in contrast with the order for ionic association constants of their perch1orates, Ba > Sr > Ca, obtained from our conductometric measurements.
