    The solution then gets foggy/cloudy and white snowlike precipitate is floating within the solution. Heat is added along with a stir bar. The stir bar starts stirring at minute 7. It begins to dissolve the white powder as it spins. At minute 26 the solution becomes clear with barely any flakes left. Sulfuric acid is then added and white flakes are formed. More acid is added until the pH paper turns red. The round bottom is filled with white precipitate. The precipitate is put onto a hirsh funnel that uses vacuum filtration to isolate the precipitate. The product is then added to a beaker with D.I water and heated. It’s put through the hirsh funnel . 3.68 grams of salicylic acid is recovered. The melting point is tested to compare to a perfect sample. The melting point is 146C0. The product is dried and added to a beaker with D.I. water and 10mL of acetic anhydride and 20 drops of concentrated sulfuric acid. This product is chilled to produce crystals. Its then filtered using a hirsh filter using vacuum filtration. Recrystallized and filtered one last time. The product is now acetylsalicylic acid…

    Discovering the Mystery of Eleven Test Tubes

    Eleven mystery test tubes labeled from K-1 to K-11 contained: 6M H2SO4, 6M NH3, 6M HCl, 6M NaOH, 1M NaCl, 1M Fe(NO3)3, 1M NiSO4, 1M AgNO3, 1M KSCN, 1M Ba(NO3)2, 1M Cu(NO3)2 respectively. The contents of the test tubes were determined by chemical experiments. Solution K-1 contained NiSO4 because when solution K-9, ammonia which was identified by its pungent odor, was added, an inky dark blue color was made. Iron (Fe (NO3)3) was determined to be in test tube K-2. KSCN was found in test tube K-11 since Fe (NO3)3 and KSCN makes a bloody color when mixed together. Flame tests were conducted in which K-8 burned green which identifies Cu(NO3)2, and the solution from test K-10 burned yellow orange which indicates NaCl. Solution from test tube K-5 turned red litmus paper to blue which indicates a strong base (NaOH). Solutions in test tubes K-4 and K-6 are both strong acids which turned blue litmus paper to blue. Silver nitrate (K-7) produces precipitate with both acids and Barium nitrate can only produce precipitate with H2SO4 and it remains clear in HCl, K-3 precipitated with K-4 but did nothing with K-6, which proves that K-4 is H2SO4 and K-6 is HCl.…

    10 Unknowns Chem II

    I found solutions #2 to be H2SO4. While doing precipitate reactions for solution #2, I found that it fizzed with two other solutions; #6 and #8. This led me to believe that since there were two carbonates in our list of solutions, solutions 6 and 8 were the carbonate solutions. This was also one of the last three solutions that I found the name of. H2SO4 is a strong base, and a PH test revealed that it had a very low PH of 1. Also already knowing that solution 6 was NaHCO3 and solution 8 was Na2CO3, I was also able to confirm solution 2 was NaOH by the following reactions:…

    Chem 112 Technical Abstract

    To begin, 5 centrifuge tubes were added 10 drops of one cation and labeled correspondingly, and the initial color of each solution was recorded. To being the metal hydroxide test, each tube was then added 6 M NaOH drop wise (about 20 drops) until a precipitate was seen. To each solution that formed a precipitate, 10 more drops of 6 M NaOH were added. This was to test to see if any solution was amphoteric, where any insoluble metal precipitate dissolved after the additional 6 M NaOH was added. The results were recorded and each solution was disposed of. To being the ammonia test, 5 new centrifuge tubes were each added 10 drops of one cation and labeled correspondingly. 15 M NH4OH was then added drop wise (about 20 drops) to each solution and the color of the solution and/or the color of the precipitate formed was recorded. 10 more drops of 15 M NH4OH was added to each solution and any changes were recorded, and the solutions were disposed of. To begin the flame confirmation tests, 20 drops of each cation were added to its labeled centrifuge tube. A Bunsen burner was then connected to the gas jet and lit to where a sharp blue cone was visible in the flame. A Nichrome loop was then soaked in HCl and placed in the flame until there was no color change in the flame. This insured there was no further solution on the loop.…

    Safety goggles were put on, hair was tied back and sleeves were rolled up. One cm of CuSO4·5H20 was added to a cleaned dried test tube. The test tube was heated until no furthered changes were observed. All observations were recorded then the substance was then disposed of in the waste container provided. 1/3 of a test tube was filled with Na2SO4 solution. An eye dropper filled with BaCl2 was added to the test tube. All observations were recorder. A 3 cm long trip of Magnesium ribbon was held above a flame of a Bunsen burner. The result of the flame should not be directly looked at. All observations were recorded. A test tube was filled 1/3 of dilute H2SO4. A sanded mossy piece of zinc mental was added to the acid and the test tube was covered. A flaming splint was brought to the mouth of the test tube. All observations were recorded. A sanded iron nail was added to a test tube and covered with CuSO4 solution. The test tube was left for several minutes. The nail was then removed and observations were recorded. An eyedropper full of lead(II) nitrate was added to a test tube combined with an eyedropper full of potassium iodide. The reaction was left for serval minutes before observations were recorded.

    Identification of an Unknown Organic Acid

    Identification of an Unknown Organic Acid

    Identifying this organic acid was an extensive task that involved several different experiments. Firstly, the melting point had to be determined. Since melting point can be determined to an almost exact degree, finding a close melting point of the specific unknown can accurately point to the identification of the acid. In this case the best melting point range was 207-209 degrees Celsius. Melting point, while very helpful in identifying an unknown organic acid, is simply not enough. Next, a series of titration experiments had to be done. In the first series, a titration is completed of sodium hydroxide (NaOH) with KHP. Three reps were completed and the resulting data led to the finding of the molarity of the sodium hydroxide. The second part of the titration series involved titrating the same prepared sodium hydroxide solution with Hydrochloric Acid (HCL). This is how the molarity of the HCL was determined. The last part to the titration series was necessary to determine the equivalent weight of the acid. The equivalent weight for this unknown was calculated to be ~197 g/mol H+ Once these titration series experiments were complete, enough data is accumulated to complete a computer search. Based on the results of the computer search the next experiment involved conducting at least one trial of pKa and, since the results contained acids that had N,Cl,Br, or S, chemical testing by sodium fusion had to completed. With all of this information combined, it was then simple to correctly identify the organic acid unknown.…
