1. Provide a general discussion of the solubility/miscibility behavior observed in procedure A-D. For part A of the procedure we worked with the solubility of solid compounds in various solvents. The three solid compounds that were worked with during this procedure were benzophenone, malonic acid, and biphenyl. These three solids were then mixed with water (highly polar), methyl alcohol (intermediately polar), and hexanes (nonpolar). When benzophenone is mixed with water the results turned out to...

non-polar while water is polar which is the reason why it did not dissolve in water. Benzoic acid dissolves in alcohol and sodium hydroxide mainly because carboxylic acids when reacted with bases like NaOH, they produce salt and water. Due to its high solubility and polar nature, phthalic acid dissolves in water. Resorcinol dissolves in water, alcohol and ether since it is acidic and the two OH groups make the system sufficiently polar, therefore it is soluble in polar solvent. Sodium naphthionate, on the...

Marcela Rodriguez Ricardo Sarabia January 16, 2013 Mariana Mendoza Alvaro Puccini Maria Quin Solubility Lab Purpose: The main purpose of doing this lab is to learn how to interpret solubility graphs and how the temperature does affects the solubility of different substances. There are other objectives of the lab which are learning what are concentrated, diluted, supersaturated, and saturated substances and how can they be identified. The hypothesis...

RECRYSTALLIZATION OF ACETANILIDE ABSTRACT Recrystallization is the primary method for purifying solid organic compounds through the differences in solubility at different temperatures. In this experiment, a suitable solvent was first determined. Acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heating water bath. The hot solution was filtered and the filtrate, cooled slowly in an ice bath as crystals started forming...
