Two immiscible liquids can be separated by a separating funnel. The liquids are poured into the funnel and the funnel is then left to stand. The denser liquid will sink to the bottom of the funnel, while the less dense liquid will float on top. The liquids can then be poured off separately.<\/p>\n<p>Statement 2 is incorrect.
