In the crystallization process after gravity filtration is carried out, a mixture of ice and water is sometimes used as a bath instead of just ice. I know that the ice/water bath can be used to cool the filtrate to around 0 C while just crushed ice or an ice-salt bath may cool the filtrate to below 0 C. An ice/water mixture instead of pure ice is used so that the solution does not ultimately freeze?? (Are there any examples where one is preferred over another?)
Thank you.
Thank you.
