Abstract
The molar solubilities for different samples of nickeloxide(NiO) in pure
dimethylsulphoxide(DMSO) were measured at 313.15,323.15 and 333.15K.The used
NiO was prepared by different methods ; precipitation using dimethyglycoxime (NDMG),
stabilizing using citrate (Ncitrate), sol-gel(NSG) and by using urea (Nu).The samples have
different morphological structure. From the molar solubilities for nano NiO, the
solvation parameters such as, activity coefficient, solubilities products, Gibbs entropy of
solvation in DMSO at different temperatures were calculated.
