You are tasked to obtain a solid product from your laboratory activity. To verify the identity of your solid product, you measured its melting point. The results shows that the material melted over a 23º C range. After the material had cooled, you measured the melting point of the same sample again and found that this time the solid had a sharp melting point at the temperature that is characteristic of the solid product. (a) Why were the two melting points different? (b) What was responsible for the change in this melting point?

After it had cooled, she measured the melting point of the same sample again and found that this time the solid HUD a sharp melting point at the temperature that is characteristic of the desired product Why were the two melting points different? What was responsible for the change in the melting point?
A student determines the molar mass of a liquid unknown by the method used in this experiment. She found that the equilibrum temperature of a mixture of ice and water was 1.0 degrees C on her thermometer. When she added 11.1 g of her unknown sample to the mixture, the temperature, after thorough stirring, fell to -3.0 degrees C. She then poured off the solution through a screen into a beaker. The mass of the solution was 90.4 g. Kf=1.86 degrees C/m How much water was in the decanted solution? What did she find to be the molar mass of the unknown liquid, assuming she made the calculation properly?

TRUE OR FALSE: 1. Solids such as naphthalene when heated will pass thru a process called condensation prior to sublimation when being purified. 2.If water and n-propyl alcohol were mixed, the separation of individual components is possible with steam distillation because these two have a wide range of boiling point difference. 3. When an impurity in the synthesized camphor such as sodium chloride is present, the sublimation technique cannot be used to purify the camphor due to the nature of NaCl. 4. Organic solvents such as hexane or ether are an excellent medium to recrystallize an impure benzoic acid 5.
