The conductance of dilute solutions of sulfamic acid in water-methanol, water-ethanol and water-isopropanol mixture were measured at 25 °C. The experimental data were processed using the Lee and Wheaton equation to evaluate the limiting conductance Λ0 and association constant Ka. The lowest dielectric constant for each type of water-alcohol mixture was about 20.
