The beginning of the lab contained a substantial amount of information detailing what chemical properties make up the structure of a salt hydrate. It provided essential knowledge proceeding to the successful completion of this lab such as the idea that hydrates are salt compounds which have formed weak bonds to water molecules that can easily be broken through the use of heat. With this information in mind, it was expected that a series of procedural guidelines following this information be used…

The goal of this experiment was to reduce Camphor into Borneol and Isoborneol using Sodium Borohydride. In this reaction, Isoborneol was the major product while Borneol was the minor product. This is a reduction reaction, where the ketone on the Camphor is reduced to form two products with secondary alcohols. First, 0.25 grams of Camphor was obtained and added to a 50ml flask and mixed with 1.5 ml of methanol. Second, 0.25 grams of Sodium Borohydride was added to the reaction mixture and…

REFLECTIONS FOR LAB 4- FRICTION Lab 4.1 to 4.3 is about all the different frictions. We did 3 different labs. 4.1 was pulling a block across different surfaces and finding the difference in friction. 4.2 was about pulling multiple blocks across different surfaces and finding the difference in friction. 4.3 was about pulling blocks but in a bigger surfaces area. In Lab 4.1 we had to pull different blocks across different surfaces. The surfaces were a tabletop, wax paper, paper towel, fine…

For this experiment, a group was employed by the Environmental Protection Agency as analytical chemists. Their goal was to identify an unknown compound that has been discovered in a landfill in their hometown. Once they identified the compound, they would then have to determine both the chemical and physical properties of the compound in order to inform the townspeople of any potential dangers. During the first week of lab, the group was given a small bottle containing an unknown white…

The purpose of this experiment was to see how single-replacement reactions change the physical matter of the original reactants. Hypothetically, the use of 2.120g of CuCl2 should react with the iron nails forming exactly 1 gram of copper. Upon starting the lab process, there was a displacement of 2.120 grams of CuCl2 into the plastic cup containing 50 ml DI water before joining the two iron nails. After the solution sat overnight, the iron nails became black in exterior color, orange copper…

Determining the Chemical Formula of Hydrated Copper (Ⅱ) Sulfate Using the Empirical Formula Introduction In this experiment, the molecular formula of hydrated Copper (Ⅱ) Sulfate will be determined. In order to determine the molecular formula, the empirical formula is needed which is the ratio of moles of one substance to another. In this experiment, it is the ratio of Copper (Ⅱ) Sulfate to water. CuSO₄・XH₂O The empirical formula can be determined if the moles of the compared substances…

Discussion There were four goals for Project 11: Identification, Properties, and Synthesis of an Unknown Ionic Compound. The first goal was to identify the unknown compound, the second goal was to determine the reactivity of the compound, the third goal was to determine the quantitative solubility of the compound in water, and the fourth goal was to find the percent yield of a product from a reaction involving the unknown compound. Determining the identity of the unknown compound was achieved…

CH 204- Introduction to Chemical Practices Experiment 1- Qualitative Analysis of Cations Sharon Alexander Kathrynn Labat TA: Yu-Chun Lin September 25, 2017 Results & Discussion This experiment was composed of three parts. In the first part, qualitative methods were used to identify the unknown cation in an aqueous solution. The cation was to be either lead or silver. If silver was present, extra steps were needed to be taken in order to confirm its presence in the…

Purpose: The purpose of this lab is to prove and discern the empirical formula of copper oxide using the Law of Conservation of Mass. This states that in measuring the mass of each component of copper oxide and determining the percent composition of each the copper and the oxygen within copper oxide it is possible to find the ratio of the elements within the compound. Procedure: In order to conduct this lab, 25.1mL of distilled water then 25.5mL of 3M HCl must be added 2.11g of copper oxide.…
