Low sodium diet

molarity of the unknown substance. I believe that it will take around three hundred drops of sodium hydroxide (NaOH) for it to be able to reach to its endpoint of the unknown substance. My reason behind my hypothesis is… Methods In this lab experiment we use a buret to measure the amount of pure water we decide that we need. A weight boat to be able to measure the sodium hydroxide(NaOH) on the triple beam balance. We also used a beaker to put our…

REFLECTIONS FOR LAB 4- FRICTION Lab 4.1 to 4.3 is about all the different frictions. We did 3 different labs. 4.1 was pulling a block across different surfaces and finding the difference in friction. 4.2 was about pulling multiple blocks across different surfaces and finding the difference in friction. 4.3 was about pulling blocks but in a bigger surfaces area. In Lab 4.1 we had to pull different blocks across different surfaces. The surfaces were a tabletop, wax paper, paper towel, fine…

give information on how the compound would react and behave in the local landfill and surrounding environment. The similarity of the qualitative results of the unknown compound and the known compound further suggested that the unknown compound was sodium sulfate. During the third week of lab, the group conducted the quantitative solubility test to determine the saturation point of the compound in water. If a precipitant formed, vacuum filtration would be used to figure out the amount of solid…

This bath bomb is small, mighty, and identical to the larger "The Sorting Hat" bath bomb that we stock. You can now enjoy a touch of luxury at a more affordable price! This almost white, ambiguous bath bomb causes bath water to change colour after a few moments. Each house has its own scent and special hidden colour as detailed below; Gryffindor, comes in a sweet, mixed spice fragrance with notes of cinnamon, nutmeg, ginger, orange and a hint of clove. This bath bomb hidden colour is red.…

Concentration of a Weak Acid Solution • Obtain an unknown acid solution (90 mL) and three 250 mL beakers. Make sure the beakers are clean. • Acquire 0.1 M of NaOH solution for this experiment and make sure to determine the specific molar concentration of sodium hydroxide utilized. • Obtain a buret and make sure to rinse it with tap water, deionized…

urine sample is, the higher the specific gravity will be as well. 2. Based on the urine color and specific gravity, Tracey is able to conclude Max’s hydration status during the different recorded stages. Before he exercises, Max’s pale yellow urine and low specific gravity level suggest that he is quite hydrated during this time. Immediately after exercise his dark yellow urine and high specific gravity suggests that he is dehydrated. Hours after his exercise his urine color and…

Purpose This lab’s purpose was to experiment how much of a syrup solution would seep through a dialysis bag at different temperatures. Procedure We prepared by filling up three dialysis bags with about 100 mL of a syrup solution. We tied knots on either end and measured the initial mass of the bags. The bags were measured in grams. Then we added water to three different beakers, each being a different temperature. One beaker was room temperature, another was heated to about body temperature…

As a result, lactose is a competitive inhibitor. In the presence of the inhibitor, the slope of the Lineweaver-Burk plot becomes the equation below. Using equation 7 along with the Km and the Vmax from series A, the Ki of Series B and C were calculated. The concentration of inhibitor for 50mM lactose was found to be 35714 μM using equation 1. Similar to the substrate concentration, the inhibitor concentration can be found using the same equation, but substituting in the inhibitor molar…

1. Fill a mason jar half-full with tepid water. Put it on the hotplate and raise the temperature to 98 degrees. Make sure you can keep it at this temperature for several hours. 2. Wash your hands. Cover the surfaces adjacent to your kitchen stove with paper towels. Place the test tube racks close to the stove on the paper towels. 3. Fill the pot with water and bring to a boil. Uncap your test tubes. Using your kitchen tongs, carefully drop your graduated cylinder, test tubes and their caps in…

To identify the unknown chemical mixture (#757), a TLC analysis was conducted using three standards (aspirin, acetaminophen, and caffeine). A TLC plate was prepared by drawing an origin line and solvent front line with a pencil. Three spot were labeled A, B, and C. A sample of each standard was spotted on the analytical TLC plate approximately 1cm from the bottom of the plate. It was then enclosed in a jar filled with 2ml of 95% ethyl acetate- 5% acetic acid. (Another laboratory group conducted…
