Abstract

The method of cooling at a constant rate was applied to determine the width of the metastable region of aqueous solutions of potassium chloride saturated at approximately 40 °C and containing 0 to 0.1 wt.% Pb(NO<sub>3</sub>)<sub>2</sub>. Lead(II) ions widen the metastable region up to a Pb(NO<sub>3</sub>)<sub>2</sub> concentration of about 0.01% at which solution is apparently saturated with the addition. Additional increase in the Pb(NO<sub>3</sub>)<sub>2</sub> concentration rather makes the metastable region narrower. The experimental data are compared with published values and discussed in terms of theories. A plausible explanation of the observed dependences is based on Glasner's theory of nucleation of KCl in the presence of Pb<sup>2+</sup> ions.
