Define melting point as it pertains to the melting point experiment. (1 pt) Define melting point depression. What is it proportional to? (2 pts) Define the term "eutectic point" and draw a diagram illustrating this concept. (2 pts) How is the melting point of an organic compound such as benzoic acid affected by impurities? (2 pts) If a sample of cetirizine (Zyrtec) having a melting point of 110-115 C is mixed with a sample of cinnamic acid (melting point = 120-121 C), then the melting point of the mixture would then be (2 pts): ) ) ) abcdon The melting point would be 115-118 C based on calculations The melting point would be 230-236 C based on calculations The melting point would be 116.5 C based on averaging The new melting point is unknown but would be expected to be higher The new melting point is unknown but would be expected to be lower The trend of the new melting point cannot be guessed at or predicted f) 1
