    Red Blood Research Paper

    • 534 Words
    • 3 Pages

    created to hold a constant pH balance. Blood has many components to help the body stay stable. the Body’s pH allows us to do everyday life without constantly being sick. A buffer is a mix of a weak acid and a conjugate base in a solution. They resist pH change when acids or bases are added to the solution. Blood is made up of red blood cells, white blood cells, platelets and plasma. Red blood cells help the body is carrying nutrients. Hemoglobin is the main component in blood and carries…

    Mgcl2 Lab Report

    • 4 Pages

    We ran MgCl2 through various tests to see if its properties match our UWC. the first test was to compare the solubility of UWC and MgCl2. We added 1mL of distilled water to two different beakers each and gradually added 1g of MgCl2 and 1g of our UWC to each beaker. Approximately after 15 minutes, both solids dissolved in the water and MgCl2 passed this test. The second experiment was the halide test to determine if there are any Cl- ions in both solutions. We added 1 mL of 6M HNO3 and 1mL of…

    • 2 Pages

    Procedure: To begin this experiment all of the equipment was collected. The materials used in this experiment were a small plastic weighing dish, oxalic acid, a 250 mL Erlenmeyer flask, distilled water, a buret, NaOH solution, a 150 mL beaker, funnel, and phenolphthalein indicator. Before the experiment began the buret was cleaned with distilled water, a buret brush, and dish soap. The buret was completely washed out in order to not cause any faults in the results of the experiment. Once the…

    Buffer is made up of weak acid and its conjugate base. The pH of a buffer is determined by the ratio of unprotonated and protonated species, as described by the Henderson-Hasselbalch Equation: Since buffer in its buffering region contains both unprotonated and protonated species that can accept and donate protons, respectively, it resists sudden change in concentration of protons accompanying with the addition of certain amount of strong acid or base depending on the buffer capacity.…

    Stoichiometry Lab Report

    • 2 Pages

    The number of moles of hydrochloric acid neutralizes for the three trials (2,4,5) were calculated using stoichiometry. It was calculated for trial 2 by convert 4.88 mL NaOH to L by divide by 1000 mL. Then, to get to mol of NaOH the molarity of NaOH was multiplied by 0.00488. Then to get from NaOH to HCl, the mole ratio 2 HCl to 1 mol NaOH was multiplied by 0.00122. To get the amount of HCl per beaker, 100 mL of HCl was divided by 1000 mL to get 0.1 L. Then, the liters were converted to moles by…

    CONCLUSIONS: The purpose of this experiment was to find the concentration of the unknown base (NaOH) through a titration. In the experiment, it took 0.95 mL of NaOH with a concentration of 0.53 moles to neutralize 5.0 mL of a 0.100 M of HCl. In the expected result, the concentration of the NaOH was 0.50 moles. The percent error for the lab was only 6%, which means the lab had a fairly high accuracy. Differences between the expected results and the actual result would be caused by the sources of…

    Buret was rinsed with water and NaOH, and followed by filling with NaOH solution made in the first week of lab. An acid of unknown concentration was prepared by the instructor and given for analysis. 25.00 mL of the acid was transferred into an Erlenmeyer flask using a volumetric pipette and 2-3 drops of phenolphthalein were added. The resulting solution was titrated with NaOH to achieve the faint pink endpoint and [unknown] was calculated according to the volume of NaOH used. The purpose of…

    His current medications include metformin (Glucophage), insulin human regular (HumuLIN R), warfarin (Coumadin), furosemide (Lasix), carvedilol (Coreg), captopril (Capoten), potassium (KDur), thiamine (Thiamilate), multi-vitamin (One-A-Day), trazadone (Desyrel), moxifloxicin (Avelox), amiodarone (Cardarone), and a nitroglycerin patch (Nitro-Dur). The ECG revealed that the distal two thirds of the left ventricle were akinetic, and his cardiac catheterization revealed that he had an 80% occlusion…

    Six year olds. Teenagers. Adults. Seniors. All of these age groups would come watch Kiss perform. After the show everyone would tell Kiss how much fun they had. Kiss went through all of these troubles and still ended up becoming one of the biggest bands ever. Gene Simmons and Paul Stanley formed Kiss who as a group, created a legacy because of their costumes and behaviour. They had a hard time finding other members, an amazing legacy, and a member going away. The band Kiss was all in separate…

    the endpoint of a solution. It also allows us to see a physical change, thus resulting in a more accurate measure of how much was titrated. Citric acid is a weak acid, making it best titrated by using a strong base, such as sodium hydroxide. The combination of a weak acid and a strong base would result in an endpoint that corresponds to the range of phenolphthalein indicator approximately a pH of eight. Image A Phenolphthalein is composed of C14H20O4, as shown in the image above and can…
