We present investigations of aqueous crystallization kinetics of several inorganic coordination complexes studied by a droplet technique. Video monitoring of K3Fe(CN)6 and K2CrO4 solutions which are driven to supersaturation at varying rates was used to extract parameters relating to homogeneous nucleation. The size of the droplet was controlled to ensure an upper limit of one crystal formed per drop. Comparisons of the data obtained vs. static, batch techniques will be presented.
