Table 1: Recrystallization of acetanilide |
||
| Compound | Mass (g) | Melting Point (°C) |
| Acetanilide | 2.10 | 108-117 °C |
| Recrystallized acetanilide | 1.86 | 112-115 °C |

| Table 2: Recrystallization of trans-Cinnamic acid | ||
| Compound | Mass (g) | Melting Point (°C) |
| trans-Cinnamic acid | 0.52 | 128-140 °C |
| Recrystallized trans-Cinnamic acid | 0.38 | 131-134 °C |
| Percent recovery | Fill in | |
Percent recovery = amount of substance you actually collected / amount of substance you were supposed to collect, as a percent
You want to purify 10 g of acetanilide that has been contaminated with 0.2 g of cinnamic acid. Solubilities in water of the two compounds are given in the following table
| Table 3: Mixture of Compounds | ||
| Compound | solubility at 20° C (g/10 mL) | solubility at 100°C (g/10 mL) |
| trans-Cinnamic acid | 0.22 | 6.67 |
| acetanilide | 0.029 | 0.680 |
