In organic synthesis, we are often using drying agents such as sodium sulfate, magnesium sulfate, etc. to dry our solutions. Which of the following is true? (There are more than one correct answers)

If the solution is translucent and the drying agent flows freely in the mixture, the solution is relatively dry.

Before adding a drying agent into the solution, the organic layer should be evaporated off. There is no water present in the organic layer.

The solution is completely dry when you no longer see any solid left in the solution.

Before adding a drying agent into the solution, the aqueous layer should be separated as thoroughly as possible from the organic layer.

Fill the solution container with drying agent. Make sure the drying agent level equal to the solution level.

Add a small amount of drying agent first, swirl the mixture and allow it to settle.

Place the solution container into an oven after the drying agent is added.
