"Solubility" Essays and Research Papers

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...

354-355 Experiment 2 SOLUBILITY 1. Part A. Solubility of Solid Compounds. Use your observations to complete the following table, rating each system as soluble, insoluble, or partially soluble. Organic Compound Benzophenone Water Methyl Alcohol Hexane Malonic acid Biphenyl 2. Considering the polarities of the compound and the solvent and the potential for hydrogen bonding, answer the following: a) There should be a difference in your results between the solubilities of biphenyl and benzophenone...

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...

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...

Effect of Temperature on Solubility Lab Purpose: What is the solubility of minerals in water? What is the relationship between temperature and solubility? Hypothesis: If salt and sugar are each tested in water of varying temperatures, then salt and sugar's solubility will increase as the temperature also increases. Materials: Two 250 mL beakers Tap water 100 mL graduated cylinder Hot plate Two petri dishes Glass stirring rod Salt Sugar Thermometer ...

differences in solubility. Insoluble impurities and colored impurities can be removed from hot solvent through the use of activated carbon and filtration. Soluble impurities remain in the cold solvent after recrystallization. The desired product should be as soluble as possible in hot solvent and as insoluble as possible in cold solvent. The selection of solvent is, therefore, critical to the successful recrystallization. Recrystallization is a purification procedure, which requires solubility of the...
