Crystallization and filtration
WebTo do this, the damp sand in the filter paper can be transferred to another sheet of dry filter paper, and, by folding and dabbing, the sample can be dried. If necessary, another piece of filter paper can be used. Students often like to present their specimens in small bottles for approval, so a spatula could be used to accomplish this. While ... WebVarious steps are involved in the process of crystallisation. They are 1. Preparation of the solution 2. Filtration of the solution 3. The concentration of the solution (by heating) 4.
