Preliminary Test and Solubility Classification of Organic Compound Keene Louise Topacio‚ Christopher Jay Robidillo Abstract The experiment focuses on how to classify organic compounds by its functional groups. It is done by preliminary test and with the solubility test. Preliminary test used two known compounds also the unknowns. Physical state‚ color‚ odor‚ and ignition test were noted. The known compounds are inorganic and organic compounds. A comparison is made from the observation in the unknown

Use solubility of group 2 to figure out periodic trends as well as identify unknown captions Introduction The goals of this experiment were to determine periodic trends in solubility of group 2 metals. The other goal was to use our knowledge of solubility’s to identify cations present in a single unknown Xe and double unknown XXe. I have hypothesized that the solubility

Williamson‚ Macroscale and Microscale Organic Experiments‚ 2nd Ed. 1994‚ Houghton Mifflin‚ Boston p385 Revised 10/15/03 Prelab Exercise: Give the detailed mechanism for the acid-catalyzed hydrolysis of methyl benzoate. Introduction: The ester group is an important functional group that can be synthesized in a number of different ways. The low-molecular-weight esters have very pleasant odors and indeed are the major components

The methylene blue staining procedure is used to measure yeast viability based on the assumption that the methylene blue will enter the cells and be broken down by living yeast cells that produce the enzymes which breaks down methylene blue‚ leaving the cells colourless. The non- viable cells do not produce this enzyme (or enzymes) and as such the methylene blue that enters the cells are undegraded causing the cells to remain coloured (the oxidized form concentrates intracellularly). The coloured

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.

CM1191 Experiment 1: Study of Solubility Equilibrium 1. Abstract The aim of this experiment is to determine the relationship between the solubility of potassium hydrogen tartrate (KHC4H4O6) and temperature. Titrate a known concentration of NaOH against a saturated solution of KHC4H4O6 at different temperatures to obtain the concentrations of KHC4H4O6‚ and hence the solubility product constant of KHC4H4O6 at various temperatures. It was found that the solubility product constant of KHC4H4O6

rules to determine how soluble each chemical is and if it is at all. This is what we call solubility laws. These laws show what chemicals are soluble and which ones are insoluble. They also describe what chemicals can be dissolved and what chemicals cannot dissolve. These chemicals are them recorded on Solubility tables which list solubility and how soluble the chemicals are. According to Busch (2015) the Solubility Rules are as follows: 1. Salts containing Group I elements are soluble (Li+‚ Na+‚ K+
