  • Reaction Stoichiometry Lab Report

    the metals were. Continuing, we also noticed that part A and B differed in terms of what the unknown metals turned out to be for each one. Part A's unknown metal eventually was found to be beryllium, while part B's unknown metal was determined to be Barium. In closing, after following the steps and performing the calculations using the formulas we were able to determine that the two unknown metals were Beryllium and…

  • Hydrated Cobalt (II) Ion Complex Was Refrigerated

    favours the products and results in a purple colored solution. 6. Cr2O7 2+ (aq) +2OH- (aq) ⇌ 2CrO4 2- (aq) + H2O (l) 7. n 8. Barium dichromate appeared as a fairly clear/orange solution, while the barium chromate was a milky orange colour due to the presence of precipitates. The solubility of barium dichromate was more soluble since the solution was still visible relative to barium chromate in which the solution was cloudy and non-transparent. 9. No precipitation was formed in K2Cr2O7 because…

  • Aluminum Sulfate Observation Essay

    Reaction # Observations Equation 1 We mixed Aluminum Sulfate with Barium Nitrate in two test tubes. The Barium Nitrate is a clear liquid that had no smell. The Aluminum Sulfate also was a clear liquid with no scent. When mixed, the center of the liquid turned into a milky white precipitate. After 2 minutes the white substance sank to the bottom while the clear liquid sat on top. Al2(SO4)3(aq)+3Ba(NO3)2(aq)--> 2Al(NO3)3(aq)+3BaSO4 (s) 2 First we felt the material of a piece of Magnesium.…

  • Inorganic Chemistry Experiment 3: The Identification Of Unknown

    identified as zinc carbonate due to evolution of CO2 on addition of sulphuric acid. Among the soluble solids, two (1 and 12) formed precipitates in sulphuric acid. One was expected to be Barium chloride and to react with silver nitrate. Hence, (14) and (13) were reacted with 1 and 12. This led to the identification of 1 as barium chloride and 13 as silver…

  • Strontium Research Paper

    has atomic number of 38. It is an alkaline earth metal, and is a soft white yellowish metallic element which has highly reactivity chemically. It’s properties are mostly intermediate between aand similar to those of its group neighbors calcium and barium. When it is exposed to air, the metal forms a dark oxide layer. Strontium has 38 protons, 50 neutrons, and 38 electrons. The electron configuration of Strontium is 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(10) 4s^(2) 4p^(6) 5s^(2) or [Kr] 5s^(2).…

  • Achalasia Case Study

    doctors may rather perform an endoscopy. In this procedure, the doctor inserts a tube with a tiny camera on the end into the esophagus to look for problems. Another diagnostic method is a barium swallow. If you have this test, barium is prepared in liquid form. The doctor will then monitor the movement of barium down your esophagus with the help of X-rays. Treatment: Treatments for achalasia include: 1. Oral medications, 2. Stretching of the lower esophageal sphincter (dilation), 3. Surgery to…

  • Sodium Hydrate Lab Report

    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…
