Solubility equilibrium

Analysis: A1 vs. E1: Solubility with water (H2O) This test consists of two hydrocarbons, a cyclohexane and a cyclohexene, being added to water to test their solubility. Both the cyclohexane and cyclohexene reacted the same way after the water water was applied. Each chemical stayed afloat of the water although the physical/qualitative properties remained unchanged. The insoluble nature of the results in this test can be explained through the “like dissolves like” notion, where only polar…

implemented, and the percent recovery for each compound will be computed.

Paper Mache What is papier mache? Papier mache is a composite material usually including pieces of paper or pulp, sometimes reinforced some sort of textile, and held together by an adhesive. There are two main ways to make papier mache. The first and simplest way is to tear strips of paper and glue them down over your mold. The second way is obtained by soaking the paper or boiling it in hot water, creating a material known as paper pulp, to which then glue or adhesive is added. With either…

Young Abstract The introduction of this lab report exposes the reader to the different scientific concepts that are to be used such as melting point calculations, retention factors, and solubility in various aqueous solutions. The experimental provides the basics of using a melting point apparatus, determining solubility, and performing thin layer chromatography. In the results section the findings of my experimental are tabulated and presented in a well-organized manner so that the reader can…

crystallize under such low temperature. In part II, the filtrate now contains more chloride and sodium ions, so NaCl is to be removed next. Since NaCl is the least soluble out of the four possible salts at the majority of temperatures, but does not change solubility very much with the change of temperature. Therefore, the best way to crystallize NaCl is by evaporation. Through evaporation, the concentrations of sodium ions and chloride ions increased. The concentrations of the ions were so high…

Solubility of Chemical Compounds Lab Victoria Chanderpaul Tasneem, Zarrin Ms. Rungee February 6, 2018 February 13, 2018 Reaction of Chemical Compounds When Added to Water Introduction/Purpose: The purpose of this lab was to gain an understanding of how different chemical compounds react when added to water. Hypothesis: If different pure substances are dissolved in water, then there can be an understanding of the difference between the solubility because each chemical compound have…

Summary The goal of the experiment was to determine weight % of sulfate inside an unknown sample compose of Na2SO4. The sample was dried, weighed and dissolved in water and hydrochloric acid. Barium chloride was then added in excess to drive the precipitation process to completion. Heat was use to digest the precipitate before it was filtered through an ashless filter paper and ignited to constant weight. From mass of the sample and mass of the precipitate, the percentage of sulfate in the…

Introduction: Solubility is the “ability for a given substance, the solute, to dissolve in a solvent” . The effect of temperature on solubility is that when heat (energy) is added, it increases the speed on which molecules and particles move, therefore making it a quicker process. Where as with cooler temperatures there aren’t as many particles because the solvent doesn’t contain as much energy as warmer temperatures, therefore not dissolving as well as it could if it was warmer. To make jelly…

contaminate environment by releasing, but are aquatically toxic. Synthesis:- The methylimidazolium and pyridinium ions have proven to be good starting points for the development of ionic liquids. Properties, such as melting point, viscosity, and solubility of starting materials and other solvents, are determined by the substituents on the organic component and by the counter ion. Many ionic liquids have even been developed for specific synthetic problems. For this reason, ionic liquids…
