Dhwaihi Chem 151 Lab Prelab Assignment for week 3 Chemical Separation Procedure: Separating the sample: First place a small amount of the spinach provided in the mortar‚ just enough to cover its bottom; combined with the sand provided to break down the call walls. A 1:1 mixture of hexane and acetone was determined to best solvent for this extraction. Knowing this add one mL of the pure hexane and one mL of the pure acetone to the mortar. Grind the contents until the cell walls have been adequately

Extraction of pigments 3-4 baby spinach leaves were gathered and placed into a mortar with a small amount of sand. 8mL of methanol was measured out and added to the mortar. A stemmed funnel lined with a filter was clamped and placed into a 125mL separatory funnel (with stopcock closed). The spinach was crushed with a pestle until it turned a dark green
