What should be included in the physical assessment of solubility?
- Because the physical assessment of solubility does not involve a specific or stability-indicating assay,it is recommended that some attempt be made to verify the stability and purity of the solute. Also, evaporation of the solventshould be carefully monitored and controlled during the solubility measurement performed by this method.
How to treat short range order in crystalline solids?
- • An improved method to treat short range order in crystalline solids was developed in 1951 by Kikuchi and called Cluster Variation Method (CVM). • It can treat arbitrarily large clus ters of lattice sites but the entropy expression must be derived for each lattice. Therefore, even for binary systems it can be ……….. to use.
