Consequently a number of other groups demonstrated that ionic liquid/CO2

mixture by using the techniques of decantation and sublimation. By performing these techniques‚ we examined our solutions such as SiO2 (sand)‚ NH4Cl (ammonium chloride)‚ and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions‚ we made calculations by finding the percent mass of each solution once the experiment was completed. In our findings‚ we were able to determine the mass of the determined and the percent recovery of matter. The outcome

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

In part 1 the results of the solubility do not agree with the with rules of solubility most likely because we put too much solid in the test tubes and not enough water to dissolve it. They should have dissolved because the anything with nitrate should be soluble. With the pH‚ when the mixture where compared with the chart all of them except NaCl where a shade of blue which means that they have a pH of 8-14‚ depending on the darkness of the shade‚ meaning that they are a basic solution.

Lab 3: Solubility of Organic Compounds Objectives: Understanding the relative solubility of organic compounds in various solvents. Exploration of the effect of polar groups on a nonpolar hydrocarbon skeleton. Introduction: The solubility of a solute (a dissolved substance) in a solvent (the dissolving medium) is the most important chemical principle underlying three major techniques you will study in the organic chemistry laboratory: crystallization‚ extraction‚ and chromatography.

Utilizing the Lab Results PS2200 - Criminal Investigation Unit 04 Assignment 01 As the lead homicide investigator for this case I had recently learned that the crime lab has concluded that the finger print that was recovered belonged to the boyfriend‚ they were from a piece of notebook paper found under the body of the victim. Interviews are conducted in criminal cases for the purpose of gathering information from people who have‚ or may have‚ knowledge needed in the investigation. (Swanson

The results of the investigation support the hypothesis that water‚ which exhibits greater polarity‚ is able to dissolve a greater mass of KNO3 at lower temperatures compared to tested concentrations of Ethanol ranging from 12.5% to 30%. Furthermore‚ the results of the graph 1 show correspondence to the dielectric constant of each solvent as both the starting solubility of the solubility curves and the dielectric constant of the

Lab Report Ionic and Covalent Bonds Lab: Ionic and Covalent Bonds Introduction: The purpose of this experiment was to explore the properties of chemical substances that can be used to identify the types of bonds in a chemical substance using a laboratory procedure. The two types of bonds being identified were ionic and covalent. Based on a substance’s properties‚ how can you determine whether its bonds are ionic or covalent? This is the question I posed before starting the experiment.
