Abstract

Induction periods have been measured for various supersaturated aqueous solution of 1mol% of Rb2CO3 doped potassium acid phthalate by direct vision method. Nucleation parameters such as radius of critical nucleus, Gibb’s free energy change have also been investigated. The critical supersaturation ratio for the Rb2CO3 doped KAP solutions at 45˚C was evaluated to be 1.002615. Based on the thermodynamical approach correction was made to the interfacial energy. An attempt has been made to calculate the nucleation parameters corresponding to the critical supersaturation ratio using the modified classical nucleation theory..
