C. Use a ring clamp to hold the separatory funnel.

D. Vent several times.

Explanation:

The separatory funnel is an instrument used to separate a mixture of two immiscible solvents. The solvent with the higher density settles below, while the one with the lower density remains above.

Important precautions to note when using the separatory funnel are;

1. Use a ring clamp to hold the separatory funnel. This is necessary because it will allow a measure of stability during the separation process.

2. Vent several times. This is necessary in order to balance the atmospheric pressure above and below the funnel. So the stopper on top of the funnel should be vented several times during the process.
