Extraction Extract the organic solution three times using 15-mL portions of 3 M hydrochloric acid. Be sure to hold both the stopcock and the stopper of the fun- nel tightly and frequently vent the funnel by opening its stopcock (Fig. 2.61). Identify the aqueous layer by the method described in Section 2.21. Combine the three acidic aqueous layers from the extractions in an Erlenmeyer flask la- beled "HCI Extract." Return the organic layer to the separatory funnel and extract it two times using 15-mL portions of 3 M sodium hydroxide solution. Combine these two aqueous layers in a second flask labeled "Hydroxide Extract." Transfer the organic solution into a clean Erlenmeyer flask containing two spatula-tips full of anhydrous sodium sulfate and labeled "Neutral Compound." Let this solution
