Charmi Balsara #3 Chem 3AL, Section 204 TA: Raymond La Lab 1: Investigating Solubility and Acid-Base Reactions Purpose To understand how acid-base properties and polarity affect solubility and chemical reactions. Discussion In part I, according to the “like dissolves like” property, hexane, as a nonpolar molecule, dissolved the nonpolar diethyl ether, dichloromethane, ethyl acetate, and acetone. However, as polar molecules, ethanol and water are immiscible in hexane. In part II, as a polar molecule, water does not dissolves (immiscible) with the nonpolar diethyl ether, ethyl acetate, and toluene, which explains the layers in each of the solutions (6B). Acetone and ethanol dissolve in water to form a clear liquid because they are both polar. Even though dichloromethane is polar, it does not completely dissolve in water because there is no place for hydrogen bonding on the dichloromethane. In part III, water dissolves the polar ethanol and 1-propanol to form clear liquids (7T). Water’s solubility with 1-butanol and 1-pentanol decreases so that 1-butanol is only partly soluble in water, while 1-pentanol in water forms two layers (7T). Even though the two alcohols are polar, as they gain more nonpolar carbon chains, it gets harder for the polar O-H
