What is the molality of your salt water solution? Show your work? #2). What is the theoretical Boiling Point of your salt water solution? Show your work. #3). What is the percent error from your measured boiling point of your salt water solution? Page 2 Boiling Point Elevation #4). If you were to use this same mass of Aluminum Chloride, what would be the boiling point? Show your work. #5). Using your boiling temperature of water as a reference point, what is the molality of the Saturated Salt Water based on its boiling point? Show your work. #6). Using your measured density, and determined molality, what is the Molarity of Saturated Salt water solution? Show your work. Part B -Intermolecular Forces #7). Using your measured boiling points only, rank the five solutions (Acetone, Isopropanol, Hexane, Sat. Salt Water, Water) in order of strongest molecular forces to weakest. #8). Using your measured drops of solution able to stay on a penny, rank the five solutions (Acetone, Isopropanol, Hexane, Sat. Salt Water, Water) in order of strongest molecular forces to weakest. Page 3 1 Boiling Point Elevation #9). Of the four main types of intermolecular forces (Dispersion Force, Dipole-Dipole Force, Hydrogen Bonding, lon-Dipole Force), indicate which forces are found in each of the tested materials. Acetone - Isopropanol - Hexane - Saturated Salt Water - Water- #10). Using your data, what is the order of intermolecular forces from strongest to weakest? Explain your choice and refer to your collected data to prove your listed ranking Part C-Miscible Solvents #11). After the liquids separate, what is the top liquid? #12). After the liquids separate, what is the Bottom liquid? #13). What is the percent of isopropanol recovered through this separation? Show your work. #14). Why would adding salt cause the liquids to separate? Page 4
