“…However, the electric properties of the droplet under the supersaturated state are seldom reported. Only in 1963, Torgesen et al [4] carried out the measurement of electrolytic conductance of ammonium dihydrogen phosphate solutions at a given temperature in the saturation region.In this work, the cell and system for measuring the electric properties of single aerosol droplet are designed and applied to the NaClO 4 aerosol droplet. The conductance and capacitance are obtained in different RH and…”

By using the measuring system previously designed by the authors, the conductance of KCl, NaCl and NH 4 Cl microdroplets is obtained in the whole measuring RH range, especially in the supersaturation region, which cannot be acquired from the bulk solutions and fills the gap of lack of experimental data of conductance under the supersaturated state. The ERH and DRH of these three kinds of microdroplets observed from a microscope are 80.5% and 95.4% (KCl), 75.7% and 93.3% (NaCl), and 69.9% and 96.6% (NH 4 Cl), respectively. In addition, it can be found from the dependence of conductance on RH that conductance is very sensitive to the existence of water molecules inside the microdroplet and the threshold of the deliquescence process can be predicted by the variation of conductance.
