experiment 3: acid, base, neutral separation (liquid-liquid extraction, drying, recrystallization) purpose: the purpose of htis lab is to show that immiscible solvents form separated layers based on their relative densities, to become familiar with the technique of extraction of a solute from one solute to another based on partition coefficients, and how this partition coeffiction can be affected by the pkas of acids and bases. also, this lab illustrates the importance of flow charts and the concept that drying agents remove traces
