Hi I was just wondering why we use ice cold solvent when performing a filtration before vacuum filtration? What exactly does it do? Like ice cold alcohol? I know it allows filtration to be more efficient, but how exactly?
Filtration-ice cold solvent is a method used in chemistry to separate a solid from a liquid by passing the mixture through a filter while keeping the solvent at a low temperature.
The purpose of using ice cold solvent in filtration is to reduce the solubility of the solid in the liquid. This allows for a more efficient separation of the solid from the liquid.
Most commonly, water is used as the solvent in filtration-ice cold solvent. However, other solvents such as ethanol, acetone, and methanol can also be used depending on the solubility of the solid in the solvent.
The ideal temperature for an ice cold solvent in filtration is typically between 0-5 degrees Celsius. This temperature range allows for a good balance between solubility reduction and maintaining a liquid state of the solvent.
Filtration-ice cold solvent offers several benefits including a more efficient separation of solid and liquid, reduced risk of contamination, and improved purity of the separated substances. It also allows for the recovery of the solvent for future use.
