The effects of addition of electrolytes on the foam stability, surface tension and surface viscosity of 0.1% solutions of Rodium laurate adjusted to pH 10 have been studied. The electrolytes employed had no significant effect on surface viscosity, but, produced a progressive lowel,ing in surface ten8ion which is a function of cation concentrabion. The size and concentration of the hydrated cations were found to influence foam stability; thus the alkali metals increase foam stability in the order Li < N a + < I
