Chemical Compound Of Alum And Souric Acid
The purpose of the first part of the experiment was to produce a chemical compound which was the alum crystals by using aluminum, potassium hydroxide and sulfuric acid. After the compound was present, the purpose of the second part of the experiment was to make sure that the compound that was formed in the first half of the experiment was actually alum. Some of the experimental techniques that were used in this experiment was filtration using the Büchner funnel vacuum filtration, recrystallization using an ice bath, melting point using the Mel-temp equipment and water of hydration using heat to dehydrate the compound. For the experiment, the theoretical yield appeared to be 18.90g of alum and the actual yield was 12.198g of alum, which resulted

    To What Extent Do Solid Crystals That Form Better Between Sugar And Unionized Salts

    In this experiment I conducted a test to see if solid crystals would form better between sugar and unionized salts. Also under two different temperatures, would this effect the size at all. My overall hypothesis was to test at what rate and size would crystals grow in sugar vs salt at different temperatures, and that I thought the salt would produce a greater amount of crystal deposits. My method was hanging a string from a pencil immersed in the different solutions. My results were similar in both tests.…

    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.…
