Supersaturation ratio 610 INDEX

The dependency of rate of precipitation of barite from aqueous solution on time at room temperature studied by Nielsen (1958) suggests that the precipitation of barite from solutions of high levels of supersaturation (i.e., more than 30 as saturation index (S.I.) which is defined as the ratio, where A sp is the solubility... 

The status of solid phase can be determined by Saturation Index (SI), which is the ratio of IAP and A. p. If SI > 1, then the solution is supersaturated with respect to the solid phase and if SI < 1, then the solution is undersaturated with respect to the solid phase. At equilibrium, SI = Any precipitate formed at high concentrations can potentially dissolve, when the concentration of the ion decreases. 

The ratio of crystal growth rate rg = dx/dt, and the nucleation rate dn/dt, or Bg, is plotted as the crystal size or grain index against the supersaturation a ...
