    • 4 Pages

    Acid Rain Lab #1 Chem. 1 20 February 2016 Concordia University Texas Angelina Luna angelinaluna97@yahoo.com Chem 1- Sect C Acid Rain Lab #1 Professor Koeck Abstract In this experiment our main objective was to create three gaseous oxides CO₂‚ SO₂ and NO₂ by using data that was collected using a pH sensor which was connected to a laptop with LoggerPro and Vernier. We created the gases by bubbling each gas into the water to create the three acidic solutions we were looking for. Once that

    In this TLC lab‚ we explored the relative polarities of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine based on their functional groups. The most overall polar analgesic is considered to be the analgesic that contained the most polar function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen

    The solubility of calcium hydroxide Aim: to find out the solubility of a substance that only partially dissolves in water. Method: place about 100cm3 of distilled water in a flask and add about one spatula of solid calcium hydroxide. Stopper the flask and shake well for one minute. Leave to stand for at least 24 hours. Titrate 10cm3 samples against 0.05 mol dm-3 hydrochloric acid solution using methyl orange as an indicator. Obtain enough results to calculate an accurate average‚ and then

    • 8 Pages

    Results and discussion The aqueous solubility of midazolam is a function of both the imidazobenzodiazepine ring opening‚ which is a fully reversible process‚ and the ionization of the drug molecule play an important role in the supramolecular complexation with water-soluble cyclodextrins (Loftsson et al.‚ 2001). Therefore‚ the total charges were assessed from the acid dissociation constant determined for different forms of midazolam as depicted in Figure 1. First‚ predicted negative decimal logarithm

    pH Readings: From the pH results recorded from the two water sources‚ we can clearly see that Kleinfontein Dam has the higher pH levels‚ which indicate poor and unsafe water conditions. From Article two‚ we can see that a High (7.5) or Low (5.5) pH level is very dangerous and harmful to humans who come in contact with the water. The pH Level recordings at 8 and 9 are extreme dangers if they were to come in to contact with humans and also they are way over the borders which is not acceptable at

    Lab: Comparison of Three Isomers of Butanol Pre-lab: 1. Write the general reaction of an alcohol and HCl. 2. What would the solubility be of an alcohol in water. 3. What would the solubility be of an alkyl halide in water? 4. What is the purpose of KMnO4 in the reactions? Safety: Concentrated hydrochloric acid is corrosive and the vapour is very irritating to the respiratory system. Avoid contact with skin‚ eyes‚ clothing‚ and the lab bench. Wear eye protection and a lab apron.

    • 2 Pages

    n this lab‚ everyone got a flask which we then drew a pumpkin face on. Then we mixed 42 mL sodium hydroxide solution‚ 10 g of glucose‚ 1 mL‚ 1 L of water and Methylene blue solution and leave it undisturbed. The blue solution turned clear and when we added the yellow food coloring it turned an orange color. The solution then turned dark blue once the solution was shaken vigorously. This reaction occurred because the oxygen oxidized the methylene blue.In the oxidized state the methylene blue shows

    1. Standarization of NaOH with Potassium Hydrogenphthalate (KHC8H404) The hygroscopic nature of NaOH requires its solution to be standardized with a stable primary standard such as potassium hydrogen phthalate. The exact molar concentration of NaOH solution can then be accurately determined. 1.1) Prepare the stock NaOH solution by dissolving about 4 g of NaOH pellet in 100 mL of deionized water. Note that NaOH is a hazardous chemical which is corrosive to skin and irritant to eye‚ be cautious and

    Why Do Sodium Citrate

    IX. CONCLUSION Overall‚ our hypotheses were proved to be mostly correct. We believe that if the amount of sodium citrate is too low or too high‚ the sodium alginate solution would not form into a ball. The recommended amount of sodium citrate to be added to the sodium alginate solution was ⅛ teaspoon‚ or 0.5 grams. We supposed that if we exceeded this measurement‚ the sodium citrate would unbalance the whole solution‚ making the balls deform. If we added too little of the sodium citrate‚ we thought

    The starting material for this lab was the dialyzed sample (stored at -20ᵒ C) from the previous lab. The CM sephadex resin (taken in a 50 mL tube) was already made swollen using Buffer C (20 mM HEPES‚ pH 7.9; 1 mM EDTA; 50 mM KCl). The dialyzed sample was thawed to the room temperature and gently poured over the resin. The tube was capped and kept on a rocker at room temperature for 1 hour. The tube was then centrifuged in a HS-4 rotor at 2500 rpm (1200g) for 5 minutes at 4ᵒ C. Supernatant was discarded
