The osmotic and activity coefficients of monomethyl-, dimethyl-, and trimethylammonium chlorides in aqueous solution have been determined at 25°C by the gravimetric isopiestic method. The measurements extend from 0.1 molal (m) to 20, 17, and 15 mol-kg−1, respectively, for the three salts. In the region below 2m, the osmotic coefficients decrease in the order NH4Cl>MeH3NCl>Me2H2NCl>Me3HNCl>Me4NCl, and above 3m the order is reversed. The intermediate members of the series have identical osmotic… CONTINUE READING
