Abstract
Nucleation kinetics in the precipitation of lead iodide from dilute solutions of lead nitrate and potassium iodide was derived from measurements of the metastable region width when adding KI solution to Pb(NO3)2 solution, and also from induction period measurements on instantaneous mixing of batches of the two solutions. The nucleation order values obtained lay within the region of m = 3.5 to 4.6, which is a satisfactory agreement in view of the different nature of the two approaches.
