    When the first bag, which was made of distilled water (10 mL), was fully immersed into distilled water. Its mass almost did not change (Table 1). It increased from 11.9g to 11.3g after 15 minutes, but after it, the mass always kept in 11.3g during the last 45 minutes. For Bag 2, 10mL 10% sucrose immersed into distilled water, its mass increased with the time increased (Table 1). It showed that the weights increased 1.2g in 60 minutes. Also for Bag 3, which contained 30% (10mL) sucrose immersed into distilled water, its weight increased, too (Table 1). It increased total 3.2g in 60 minutes. The weight changes in Bag 4 (10 mL 50% sucrose) are similar to Bag 2&3, it increased 4.5 during 60 minutes (Table 1). The content of Bag 5 was distilled…

    Question How does distilled water, hydrogen peroxide (H2O2, stabilized, at 3% concentration as a dilute solution), and rubbing alcohol (70% isopropyl alcohol) affect leaves detached from their trees? Hypothesis If I submerge leaves in distilled water, then the leaves will become wet and softer (relative to their original state), because that is what happens to detached leaves after it rains. If I submerge leaves in hydrogen peroxide, then the leaves will become whitened and the distinct…

    problem in our experiment is that distilled water gain mass because there is a higher concentration of solutes while the other solutions contain a lower concentration of solutes. The different types of liquid can affect how the potatoes change or not. Our data shows that Potatoes that were put in the distilled water gained mass while the 5% salt water, 10% salt water, Gatorade, and Coca-Cola lose mass. We also concluded that liquids with high concentration gained mass while low concentration…

    In exercise 1, experiment A, the students will need a microscope slide, a coverslip, a compound microscope, carmine powder, distilled water, and a pipette. The students will begin by placing a drop of water on the microscope slide. Then they will add carmine powder onto the slide. Then they will place a coverslip on top of the solution. This will aid in mixing the solution. Then the students will observe the movement of the carmine particles on low power and high power. In exercise 1,…

    Distilled Water Case

    The isotonic solution contains nonpenetrating electrolytes that essentially increases fluid in the ECF. The nonpenetrating electrolytes in the ECF help to increase and retain blood volume, thus bring the blood pressure back up to normal. If distilled water was used, the water would just go from the ECF to the ICF as it would hypotonic the cells. This would cause the cells to become bloated and perhaps even lyse. By having the nonpenetrating electrolytes stay in the ECF, the blood volume in the…

    This result supports my hypothesis. The mass of the egg before it was placed into the distilled water and after it was taken out of the distilled water increased quite a bit. The mass before was 74.48 g and the mass after was 89.48 g, a 15 g increase. Both the long and short circumferences of the egg increased also, which further proves that distilled water is a hypotonic solution. The long circumference before the egg was placed in was 16.9 cm and 18.4 cm after the egg was taken out, which is a…

    The procedure for Lab 5 contained four parts. For Part A, a clean, dry 100 mL beaker was obtained and filled with 60 mL of distilled water. Next, the beaker was placed on a ring stand with a thermometer attached to the ring stand to record the temperature of the water. After the thermometer had been in the water for two minutes, the temperature was recorded. Following the recording of the temperature, a 10 mL pipet and a bulb was used to pipet 10.00 mL of distilled water into a clean, dry,…

    To this, add dry fruit, such as raisins or prunes. Pour this mixture into a plastic bag and squeeze the fruit into a mash. Now add the juice from the fruit cocktail, along with some water. If available, add some bread as a source of yeast. Seal the bag tightly. Now heat the bag, perhaps with hot running water, for several minutes. Wrap towels around the bag to keep it warm. That promotes fermentation. Put the bag in a safe place that will remain undisturbed for a couple of days. After…
