3 Suppose you added an additional 50 ml of water to a separatory funnel containing a compound distributed between 50 ml of ether and 50 ml of water.
( the compound you want is more soluble in ether than it is in water.) How will this addition affect
(a) The distribution coefficient of the compound?
(b) The actual distribution of the compound?
