(The gravity filtration is part of a recrystallization procedure.)
1. Gravity filtration removes most insoluble impurities.
2. Gravity filtrations are done with fluted filter paper in a long, narrow-tube funnel.
3. Gravity filtration removes most soluble impurities.
4. In a recrystallization procedure, gravity filtrations are ordinarily performed at or near room temperature.Which of the following statements regarding gravity filtration are true ?
1, and 2 are true.
Gravity filtration is removing the insoluble impurities. The next step crystallization will take advangtage that your target compound is not soluble at low temperature, only at a high temperature and this is why 4 is not correct.
