    transfers the sulfane sulfur to other receptors (eg. Cyanide) by ST enzyme, while the thiosulfate is converted to sulfite (Xin et al., 2016). As described above, the sulfane sulfur consumed may also be derived from the metabolism of intracellular amino acids (Ida et al., 2014) or self-oxidation of H2S (Chen and Morris, 1972) or catalysis of enzymes (Xin et al.,…

    1. The first part of the second experiment went according to the alternative hypothesis. The 200% saline water moved below the 100% saline water to create a layer. It did not mix with the 100% saline water or tap water. On the other hand, the second part of the second experiment did not support the alternative. Instead of moving above the 100% and 200% saline water and tap water, the 35% saline water remained at the bottom. However, it did try to move up. The reason the 35% saline water did not…

    alike when they make contact with acidic acid. Being that they become extremely reactive with the acidic acid, forming consecutively larger bubbles until the solute (being Sodium bicarbonate) had completely dissolved in the acidic acid. Using the universal indicator it can be observed that the Unknown substance or Sodium bicarbonate had both became a chunky paste, which turns into a dark green colour which signifies that it is a moderately neutral-weak acid. Finally, when comparing the Unknown…

    Martha Garcia November 10, 2017 Chemical Weathering Background Chemical Weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. It occurs in almost all types of rocks, smaller rocks are susceptible, because they have greater surface area, more common where water is, because water is important to many of the chemical reactions, when water is slightly acidic, which is called ocean acidification. Ocean acidification is…

    the residues from the manufacture of sea salt at Montpellier. He liberated the element by passing chlorine through an aqueous solution of the residues, that contained magnesium bromide. Distillation of the material with manganese dioxide and sulfuric acid produced red vapours, which condensed to a dark liquid. The similarity of this procedure to that for making chlorine suggested to Balard that he had obtained a new element similar to chlorine. German chemist Justus von Liebig supposedly had…

    Wellactin A Experiment

    • 297 Words
    • 2 Pages

    In this experiment, the components of “Wellactin A” were separated into sucrose, an unknown carboxylic acid, and an unknown organic neutral compound. The unknown compounds were identified by their melting points and the percent recovered was calculated. First, the sucrose was separated by dissolving the organic acid and the organic neutral compound in diethyl ether. 104.9% was recovered, so that means the sucrose was not entirely pure. The sucrose could have been contaminated by another…

    After thymol blue was added, the pH-buffered samples developed the colors of red, yellow, green, and blue as the pH of the solutions increased (Figure 3.1A). The pH-2 buffer turned to a light red-pink color, while pH-3 to pH-6 displayed very similar forms of rich yellow or light orange (Figure 3.1A). The neutral pH buffer solution appeared as a saffron green colored solution (Figure 3.1A). A mixture of yellow and green was apparent in the dijon color of the pH-8 buffer (Figure 3.1A). The buffer…
