Solution

I was able to determine which solution corresponded to which molarity by my knowledge of how water osmosis from high concentrations of water to low concentrations of water. I determined solution D to be the lowest molarity of 0.0 moles because the potatoes that were immersed in this solution had the highest average percent increase in mass of 23.08%. Since there is a small amount of sugar in the potato cores and the potato cores gained a large amount of mass, that must mean that there was a higher

sucrose solutions (0M, 0.2M, 0.4M, 0.6M, 0.8M, 1M) affect the mass of potato cores when in sucrose solution? Background information: Osmosis is the diffusion of water across a membrane to create an equilibrium between the levels of concentration of a solute both inside and outside the cell. In this case the solute will be sugar as the potato core will be immersed in sucrose solution. There are 3 potential states that the cell could be in depending on the type of solution: Either the solution is hypotonic

which is when the solutions are isotonic. This means that the solution has the same amount of solute on both sides. If the solution is hypertonic, it has more solute in the solution. In this situation water will move towards it. if the solution is hypotonic, it has less solute in the solution. Whereas in this situation, water will move out of the solution. The purpose of this lab is to test the effect of osmosis on cucumber slices. If a cucumber slice is placed in a hypertonic solution, then the mass

concentration between the solution and potato. For instance, in the graph that above shows the first one on x-axis is the highest mass of potato that spent 5 days in distilled water. On the other hand, the fourth one is the lowest mass, which represents 4M sucrose solution of potato. Moreover, the data proves my prediction, as water molecules from higher sucrose solution of potato moves out actively from the potato through semi-permeable membrane into the sucrose solution. In details, the important

diffusion can be seen during the lab. Also too see what solutions will cause the gummy bear to be isotonic, hypotonic, or hypertonic. This will benefit people that may eat a lot of gummy bears along with drinking sodas and juices, or water this may cause you to become more dehydrated. This will help people who like to eat gummy bears but don’t know what's best to drink with them. Hypothesis: I think that the gummy bear in the water solution will grow the most. The gatoraid will grow the least because

discovered by RJH Dutrochet in 1826, has been a significant area of interest in biology since. Osmosis is the process of diffusing water molecules through a selectively permeable membrane to dilute solutions with high concentrations of solutes until that solution has the same concentration as the solution on the other side of the membrane (Freeman, n.d., p. 96-99). An important component of osmosis is diffusion, which is when molecules or ions in the presence of a concentration gradient move from

The purpose of the experiment was to identify the concentration of an unknown solution by performing a serial dilution to provide reference for comparison. Serial dilutions are extremely useful for identifying unknown substances as the gradual discolouration of the solution allows for simple comparison. Although serial dilutions are extremely helpful for chemists, they are often used to help microbiologists reliably count the number of bacteria living in a host or an environment. Blodgett states

in sucrose solution Rebekah Schmitz Introduction: Diffusion explains the passive movement of materials into and out of the cell due to the presence of a concentration gradient from a high to low concentration across a membrane (Choinski and Karafit 2015). In this experiment, we studied the effects of differing concentrations of sucrose solutions on samples of potato material over time. This experiment focused on the effects of tonic solutions such as hypertonic and hypotonic solutions. When a cell

inside of the cell creating a hypotonic solution. The increase in water inside the cell causes the cell to become engorged and erupt. In a

used if desired. Also be careful when pouring or using any of the chemicals, because they can cause irritation and can be harmful to skin and eyes. Although some coacervates are edible, the materials used in this experiment are not food grade, so no solution or substance should be consumed during this lab. Use care when handling coverslips and slides, because they are easily broken and can be sharp. Tie back long hair, and make clothing is appropriate for a lab
