    this experiment kinetics is a huge part of it. Kinetics is explained as the reaction speed and or rate of reaction. To observe these reactions made by having reactants, sodium hydrogen carbonate, NaHCO3 known as baking soda and acetic acid, CH3COOH that is vinegar being mixed together. The products were carbon dioxide, water, and sodium acetate. Because this reaction will be based on its speed according to the difference in temperature, the higher the temperature the faster the reaction will occur creating

    Reaction rate of sodium hydrogen carbonate Introduction Aim My aim of this investigation is to determine the reaction rate of sodium hydrogen carbonate and to gain a greater understanding of the chemical and its function. The significance of this lab is mainly personal since I love baking and am curious about the chemistry of the process. However, it is also important to know how much sodium bicarbonate could be used if I were to construct my own recipe, to receive a wishful result. Research Question

    PbI2(ppt) + 2KNO3(aq). In experiment ten, claer sodium hydroxide and blue copper (II) nitrate were the reactants. When the two reactants combined together in a test tube, the solution immediately became foggy and a precipitate formed at the bottom of the test tube. Also, a double replacement reaction occurred when the two reactants were combined because the sodium in sodium hydroxide and copper from copper (II) nitrate switched places: forming sodium nitrate and copper (II) hydroxide precipitate

    Mukund Balaji, Jacob Jiang, Carolyn Zheng Honor Chemistry Mrs. Marino May 1, 2023 Thermal Decomposition of Sodium Bicarbonate Introduction: In this experiment, heat is added to a compound known as sodium bicarbonate, or in a chemical sense, NaHCO3. This compound is also known as baking soda in a domestic setting and has several uses due to its chemical nature. This lab tests the thermal decomposition of this compound by heating this compound under a Bunsen burner. There are four possible equations

  • Explain Why Some Cations Tend To Form Precipitates

    910 Words  | 4 Pages

    Introduction The majority of ionic solids are soluble in water, the ones that are not, form precipitants when two aqueous solutions are mixed. When certain cations and anions combine, they create a solid product called a precipitant, but determining factors of the formation may vary. These can form because of chemical reactions (demonstrated in this experiment) or by the change in the solubility of a substance by the change in temperature, pressure, etc. Precipitants are most likely to form in an

    The Citric Acid Cycle/ Kerbs Cycle/ TCA The Citric acid cycle is important as anaerobic glycolysis can only harvest a fraction of the energy from glucose. In the citric acid cycle there is aerobic respiration of pyruvate from step ten in glycolysis to C02 and H2O. This oxidation of pyruvate can greater a higher yield of ATP. The citric acid cycle occurs in the mitochondria where ten ATP is produced. The main purpose of the citric acid cycle is to harvest electrons from the citric acid cycle and

    Sodium carbonate (molecular formula: Na2CO3), is the water soluble sodium salt of carbonate. The pure product appears as a while, odorless powder with a strong alkaline taste. It has high hygroscopicity. It can be easily dissolved in water to form an aqueous solution with moderate alkalinity Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate) is chemical compound with the formula NaHCO3. It is a salt composed of sodium ions and bicarbonate ions. Sodium bicarbonate is a white solid that is

  • Calcium Carbonate Back Titration

    This experiment is carried out to determine the percentage of calcium carbonate, CaCO3 in the toothpaste provided with the experimental technique known as back titration. A back titration is also known as indirect titration. A known mass of toothpaste is neutralised with a known concentration and volume of hydrochloric acid, HCl. The mixture is then further neutralised by a known concentration and volume of sodium hydroxide solution, NaOH to determine the number of mole of HCl that reacted with CaCO3

    5 ml of distilled water, to this 0.25 ml ethanol, 0.5 ml of chloroform (all reagents chilled) was added. The mixture was shaken for 1 min and centrifuged at 2000 rpm for 20 min. The enzymatic activity in supernatant was determined. To 0.05 ml of carbonate buffer (0.05 M, pH 10.2) and 0.5 ml of EDTA (0.49 M) was added. The reaction was initiated by the addition of 0.4ml of epinephrine and the change in optical density/min was measured at 480nm. SOD activity was expressed as units/mg protein change

    Marble is also a tough material, although not as tough as granite. Marble can also scratch and stain easily, and also be prey to acids and corrosive substances. What you need to do is to always keep marble surfaces dry, and keep acids and other staining substances from being in contact with marble for too long. Once you do those steps, you can ensure the fine and pristine surface of your marble countertops.   So, these are some simple maintenance tips for your marble and granite surfaces. By

    2002 Words  | 9 Pages

    What is Kidney Stone?   The stone can be formed from a variety of substances, but the most common stone is made of calcium and oxalate crystallized in the urinary tract. Other types of stones include struvite, uric acid, and cystine. Although the stones themselves are painful, they may lead to more severe conditions, such as obstruction of the urethra, permanent damage to the kidney, and even life-threatening infections. I see the patient in the hospital because of the stone block into the necrotic
