In this experiment, our hypothesis was: If the liver solution is related to the buffers, then the liver solution’s pH level when mixed with HCl and NaOH will stay the same. Our hypothesis was refuted by the data showed in this lab because the pH level of the liver solution did not stay the same like the buffers did. The control groups found in this lab were buffer one and buffer two mixed with HCl and NaOH because there was no increase or decrease in the change of pH levels. There was a slight increase of pH in the liver solution when NaOH was added and a slight decrease of pH in the liver solution when HCl was added. Also the data showed a decrease in pH in the DI water when HCl and NaOH were added. When the results were compared with the steady pH level of the buffers mixed with HCl and NaOH it showed that the addition of an acid (HCl) helped the solution stay close to a steady pH level. …show more content…
Shown on the graph above, at 25 drops of HCl, buffer one and buffer two’s pH levels stayed the same, but there was a rate of change in pH levels identified within the DI water and the liver solution. Buffer one remained at the neutral pH level of 7 at 25 drops of HCl as well as NaOH. Buffer two resulted in a small decrease of pH around 2 to 3 drops of HCl, but at 25 drops of HCl it remained at a basic pH level of 9. When buffer two was mixed with NaOH it stayed in the basic pH level of 10 throughout the 30 drops of HCl and NaOH. The liver solution showed an acidic pH level of 5 when 25 drops of HCl was added. But when NaOH was added to the liver solution, there the pH level was 7 until 15 drops of NaOH was added it became a basic pH level of 8 even at 25 drops. DI water varied in pH throughout the 30 drops of both HCl and NaOH. When the DI water was mixed with HCl the pH level went from basic to acidic and stayed as a pH of 2 and a pH of

Purpose of the experiment In this experiment, we are assuming an unknown vaporized liquid has ideal gas properties. Based on this we will use the Ideal gas law and stoichiometry to calculate the Molar mass. Based on numeric and qualitative data we might make an assumption as to the identity of the liquid. Materials A special round bottomed flask Aluminum foil Pipette to transfer unknown liquid accurate digital scale A hot water bath setup. Graduated cylinder Ice bath…

heart rate which is measured in beats per minute is the dependent variable. When recording the heart rate, the test subject kept track of their pulse for ten seconds; that number was multiplied by six to calculate the heart rate for 1 minute. This lab will determine how exercise will affect the test subject’s heart rate. Hypothesis: As more seconds are added to the amount of time the test subject needs to perform the exercise, the heart rate will speed up. Materials: - Stopwatch - (3) able…

ABSTRACT We were interested in the effects of different glucose substances on the rate of fermentation produced. We hypothesized that the tube with the fructose would have a high rate of fermentation, or gas in the tube, than the tubes with apple juice orand sucrose. Using three fermentation tubes we filled each one with yeast, and water and added apple juice, 5% sucrose or 5% fructose to each tube. Then we monitored the tubes for gas production. After performing the experiment twice we found that…

Jiawei Wang Yifu Guo Christina Ge Jan 26 2014 Determining the Empirical Formula of Magnesium Oxide Background: This gravimetric analysis involves the combustion of magnesium metal n air to synthesize magnesium oxide. The mass of the product is greater than the mass of magnesium used because oxygen reacts with the magnesium metal. As in all gravimetric analyses success depends on attaining a product yield near 100%. Therefore, the product will be heated and cooled and have its mass…
