Coordination Compound Synthesis Lab
The main purpose of the following experiment is to produce a coordination compound that contains the oxalate ligand, and to determine the number of each ion in the KaFeb(ox)c·dH2O formula. In this case, the oxalate is a bidentate ligand which essentially chelates to the iron atom through two points (1). First discovered in the early 18th century by the Alfred Werner, the concept of coordination compounds was not grasped until after 200 years passed (3). Coordination compounds are composed of a central metal, ligands that bind with the metal, and oftentimes counterions. The combination of the complex ion and the counterions form a coordination compound. Subsequently, Coordination compounds are prominent and vital to biological life because of their various applications. They can …show more content…
This was possible because the mixture of potassium oxalate and iron (III) chloride is not soluble in water. This product created a precipitate, which resulted in a green crystallized product. The crystal precipitate was then isolated from the rest of the liquid substance and dried to determine the percent composition to determine the formula. The second day of the coordination compound synthesis lab consisted of performing titrations and then determining the mass of oxalate (ox) (2). An ion-exchange technique was then used to find the amount of potassium and iron (III) in the compound. Ion-exchange columns are prominent in research labs to target and remove certain ions from a solution or mixture (2). Essentially, an ion exchange column will exchange the K+ with the H+ ions and will result in a solution of hydrogen ions and the iron-oxalate anion. After this, an acid-base titration will be conducted. The hypothesis of this lab is that the creation of a coordination compound can help determine an unknown formula by determining the percent composition and conducting titration of the ions present in the

444 Words | 2 PagesAn error that could have been present during the lab includes not letting the zinc react completely with the chloride ions by removing the penny too early from the solution. For instance, the percent error of this lab was 45.6%, which was determined by the subtraction of the theoretical percent of Cu 2.5% and the experimental percent of Cu 3.64% and dividing by the theoretical percent of Cu 2.5%. This experiment showed how reactants react with one another in a solution to drive a chemical reaction and the products that result from the

1454 Words | 6 PagesWhile the solution dissolved, 50 mL of distilled water was added to a 150 mL beaker and heated on the hot plate. When the solution started to boil 2.65 grams of Na2SiO3*5H2O was added to the beaker with a stir bar and heated to a gentle boil. When both solutions began to boil, the sodium silicate solution was slowly added to the sodium aluminate. The solution was kept at 900C for 60 minutes and stirred with stir bar. After 60 minutes, the zeolite solution was cooled for 5 minutes and for the magnetized zeolite , 0.78 grams of FeCl3 and 0.39 grams of FeSO4*7H2O was added to the flask and stirred until the iron parts dissolved.
Malachite Synthesis Lab Report
177 Words | 1 PagesMalachite was synthesized using the following reaction (1): 2CuSO4*5H2O(aq) + 2Na2CO3(aq) CuCO3Cu(OH)2(s) + 2Na2SO4(aq) + CO2(g) + 9H2O(l) Based on this chemical equation, two moles of aqueous hydrated copper (II) sulfate reacted with aqueous sodium carbonate, a precipitate of copper (II) carbonate hydroxide was formed along with aqueous sodium sulfate, gaseous carbon dioxide, and liquid water. The copper (II) carbonate hydroxide precipitate is also the malachite that was obtained from the solution. It was known that a chemical reaction was occurring when the copper (II) sulfate solution was mixed in with the sodium carbonate based on the fact that the color of the solution changed from blue to light blue and the solution frothed. The malachite
Hydrated Compound
554 Words | 3 PagesAfter that, put an aluminum wire into the beaker, and after a certain period of time the solution gains color. To finish the reaction, 5 drops of 6M of Hydrochloric acid is added into the beaker to clean the solution, which means that acid dissolves all salts of aluminum that is on the solution. After finishing the chemical process, collect and use the Butcher funnel to wash the cooper because it is going to be used to a vacuum filtration. After finishing the filtration, measure the weight of the sample and dry it. Finally, Do again these two steps until notice that the subtractions of these masses are about 0.005 g, and then arrange all the chemical
Cucl3 Synthesis Lab
284 Words | 2 PagesQualitative question: Was there any CuCl2 left? There was no CuCl2 left, so the reaction went to completion. When the NH4OH was added to the solution, it did not turn blue. When NH4OH is added to a solution with copper in it, the solution should turn a cobalt blue color. However, the solution created a gel that indicates that AlCl3 was in solution, and there was minimal color change (caused by the change in the way light passes through gel).
Unknown White Compound Lab Report
1367 Words | 6 PagesAbstract: The purpose of this experiment was to identify given Unknown White Compound by conducting various test and learning how to use lab techniques. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. The results drawn from these tests confirmed the identity of the Unknown White Compound to be sodium acetate (NaC2H3O2) because there were no presence of ions and sodium has a strong persistent orange color. The compound then will be synthesized with the compounds Na2CO3 and HC2H3O2 to find percent yield.
Chemical Reaction Lab
383 Words | 2 PagesIn this lab, the hypothesis, if a chemical reaction occurs, there will be signs of a chemical change such as a change in temperature, color, and/or smell, was accepted. In each experiment, clear signs of a chemical reaction were observed. In chemical reaction #1, we put drops of vinegar onto a small pile of baking soda. The baking soda and vinegar produced bubbles of gas right as the first drop hit the baking soda, which is a clear sign that there was a chemical change occurring. This can be classified as a double replacement chemical reaction.
Lab: Iodometric Titration Of Vitamin C23
806 Words | 4 PagesThen 2.0-g solid KI was added and allowed to completely dissolve. Then 50.00-mL of KIO3 was added to the flask. This brown solution was titrated with thiosulfate until the solution was a pale yellow. At this point, 2.0-mL of the starch indicator was added, creating a dark blue solution, and titrating was continued until the solution was colorless. This process was repeated for an additional two trials.

There is error in the acetone provided thus causing the adding steps of acetone to dissolve all the complex formed in the experiment. Sodium acetate trihydrate, as a base in this experiment, causing acetylacetone to lose a proton to form acetylacetone anion, acac-. Manganese has wide range of oxidation state from +7 to -1, however, in aqueous solution, manganese with +2 oxidation state is most stable and common.
Synthesis Of Zinc Chloride Lab Report
1931 Words | 8 PagesChapter five taught about the separation of mixtures through a number of different processes. These processes use differences in characteristic properties in the elements of the mixture. For example, fractional distillation uses boiling point to separate liquid mixtures. As the liquid boils, the vapor is redirected through a tube into a different test tube and then condenses. The tube is moved into a different test tube after the first fraction concludes boiling, and then the next fraction can be extracted, etc.
Potassium Oxalatoferrate Lab Report
637 Words | 3 PagesCarbon dioxide and water in the solution were also clear. Once the solution was completely titrated, Mn7+ ions remained unreduced and changed the color of the solution to pink. The KMnO4 was added to each solution until the oxalate solution reached the end point and changed to an extremely light pink color. The change in volume in the burette of the potassium permanganate recorded in all three trials was used to calculate the moles of oxalate in the 0.100-gram compound, giving the percent composition of the compound. The three trials reacted 27.95 mL, 26.61 mL, and 25.74 mL of potassium permanganate to determine 55.7%, 53.0%, and 51.3% respectively of oxalate in the compound with a 53.3% average.
