Webincrease (leading to saturation) by solvent evaporation. 3. Slow cooling: allowing your solution to cool from a higher temperature to room temperature over a long time period (anywhere from several hours to multiple days.) 4. Vapor diffusion: allowing a solvent of high volatility to slowly diffuse into a sample of lower volatility. (Figures from: WebAnswer (1 of 4): Yes , you answered your own question. You can reduce the fast evaporation rate of a pure solvent by adding a solvent with a slower evaporation rate. An Example ; Ethyl Acetate has an evaporation rate of 4.1 (fast evaporation). where as Cylohexanone has a slow evaporation rate o...
