Midpoint of melting temperature (MP) range for pure compounds and mixtures Midpoint of MP temp range Start of MP temp range (°C) (°C) 121.50 Pure benzoic acid 121 97 80:20 mixture (benzoic acid:mandelic acid) 95 95.50 60:40 mixture (benzoic acid:mandelic acid) 93 91 40:60 mixture (benzoic acid:mandelic acid) 90 88.50 20:80 mixture (benzoic acid:mandelic acid) 88 89 118.50 119 118 Pure mandelic acid (4pts) Graph your results of the pure compound and mixture melting points. For each point, use the temperature in the middle of your melting point range. After plotting all the points, draw two best fit straight lines to connect at the eutectic composition. End of MP temp range (°C) 122 99 98 92
(5pts) Based on the intersection of the lines from your graph, what was the eutectic temperature for the mixture? Normal : BIIIU X₂ X²- ->> BIBIE fx T81 (5pts) Based on the intersection of the lines from your graph, what was the composition of the eutectic mixture?
