Final answer:
The type of funnel used to pour the solution into the sep funnel is the separatory funnel. A separatory funnel is specifically designed for separating immiscible liquids. It has a stopcock at the bottom that allows for easy separation of the two liquid layers based on their densities.
Step-by-step explanation:
The type of funnel used to pour the solution into the sep funnel is the separatory funnel (option a). A separatory funnel is specifically designed for separating immiscible liquids. It has a stopcock at the bottom that allows for easy separation of the two liquid layers based on their densities.
When the two immiscible liquids are poured into the separatory funnel, they are shaken to bring the two phases into intimate contact. After shaking, the liquids are allowed to separate into layers, and the more dense liquid is then drained out through the stopcock.
