In acetic acid at 105.7� acetamidium perchlorate has an ionic association constant KA = 0.0491 x 106 l. mole-1, a limiting equivalent conductivity A, = 79.4 cm2 Ω-1 equiv.-1, and a centre-to-centre distance between the ions � = 4.67 Ǻ. The acid-base equilibrium constant for acetamidium acetate KB = [ΣNH3Ac+ OAc-]/ [NH2Ac] increases slightly with increasing dielectric constant.

In aqueous acetic acid, 0.114-0.152M H2O, at 105.7�, oxonium perchlorate has limiting equivalent conductivity Λ0 90.7, ionic association constant KA = [H3O+ClO4-]/[H3O+][ClO4]f2 = 0.0310 x 106 and centre-to-centre distance between the ions (� = 4.84 Ǻ. The acid-base equilibrium constant for oxonium acetate KB = [ΣH3O+ OAc-]/[H2O] increases with the dielectric constant so that -log KB = 1.532+29.44/D. The autoprotolysis of acetic acid also increases with the dielectric constant.
