An extraction procedure specifies that an aqeuous solution containing dissoloved organic material be extracted twice with 10mL portions of diethyl ether. A student removes the lower layer after the first extraction and adds the second 10-mL portion of ether to the upper layer remaining in the separatory funnel. After shaking the funnel, the student ovserves only one liquid phase with no interface
