Benzoic acid can be extracted from an ether solution using an aqueous solution of sodium bicarbonate.
Liquids "flow" quickly as measured by the speed at which a small amount of liquid will spread itself out to form a puddle. What does this behavior imply about the speeds at which the individual liquid particles are moving relative to each other?
