How Does The Concentration Affect The Rate Of Diffusion
The purpose of the experiment conducted was to observe if a higher concentration or lower concentration gradient would affect the diffusion rate of the iodine moving through the starch concentration. This was shown to be an accurate experiment as with a higher concentration gradient the diffusion that did occur happened a lot faster and diffused more efficiently compared to no iodine solution and just water. This is due to the molecular collisions speeding up the experiment in the time period given because of the Soule molecules found within the given volume. This experiment can also refer to hypo, hyper and isotonic due to the two solutions being separated by the dialysis tubing (which acts as a semipermeable membrane) and diffusing from …show more content…
This is due to osmosis. The second lot of results (7.5 Concentration)show that although diffusion clearly did occur more than the first experiment, due to the indication of colour, it did not work as much as the 15 concentration. The 15 drops of iodine concentration was the more successful try in the rate of diffusion this is because it is more equivalent . There was a clear pattern throughout the three different experiments, through all 0.75 mL testings the bottom came out a dark purple and the top fogged, yet when shaken up it was a midnight purple, this occurred for all 10 experiments. The same pattern occurred for the others, except different colours due to different concentration rates. Therefore stating, a darker colour results in more diffusion meaning 1.5mL proved to diffuse more thoroughly and quickly. (INTERNET VS THIS, COMPARE AND CONTRAST) The design of this

    5. The thicker or thinner the medium is affects the rate of diffusion because the thinner the medium the quicker the dye diffuses. The thicker it is the longer it takes for the dye to diffuse. This affects nutrient transport because it can be delayed or expedited based on how thick the fluid is.…

    1. It is shown that diffusion took a lot less time when the Jelly block was smaller and had a high Surface Area/Volume ratio. The acid diffused through the 5x5x2.5mm block in about 3 minutes and 5 seconds, but the 10x10x5mm block took around 11 minutes and 25 seconds to fully diffuse, The smaller block has the high Surface Area/Volume ratio, which is why it was the fastest to fully diffuse out of the five Jelly blocks.…

    This experiment gave a visual understanding of osmosis and diffusion. The first experiment proved that solutes would move down a concentration gradient if permeable to the selective membrane. The second experiment proved different solute concentrations affect the movement of water, depending on the solute concentration inside the cell. The purpose of this lab was to look for different solutes that can cross an artificial membrane and to observe the effect of different concentrations of sucrose on the mass of a potato cell. Results for Part One suggested that the molecular weight of albumin and starch was too large to pass through the dialysis tube, but glucose and sodium sulfate molecules were small enough to pass through the dialysis tube. Also, a decrease in water weight occurred due the dialysis tube being placed in a hypertonic solution. Results for Par Two showed the potato cell having a molar concentration of 0.2734, which caused sucrose concentrations above 0.2 M to have a decrease in mass. Inversely, sucrose concentrations below 0.2 M caused an increase in mass.…

    The reason of this experiment was to identify the properties and effects of osmosis. Osmosis can be defined as the diffusion of water through a selectively permeable membrane. (Miller/Levine) Osmosis occurs when there is an area of higher and lower concentration. Osmosis is a type of diffusion. Diffusion is when molecules move from an area of higher concentration to an area of higher concentration. The three types of concentrations are hypotonic, hypertonic, and isotonic. When in comparison to another solution, a hypertonic solution has a lower concentration, a hypertonic solution has a higher concentration, and an isotonic is when the two solutions have an equal concentration. The experiment tested the relationship between the concentration of an egg and solutions of different concentrations. The hypothesis is that an egg placed in distilled water will gain mass while an egg placed in syrup would lose mass.…

    To test diffusion in a liquid, take two flasks and set them at different temperatures. To accomplish the temperature difference, one flask can be placed on ice and one should be left at room temperature. The flask should be placed on ice for about fifteen minutes until the water temperature is equal to the ice bath temperature. To indicate the rate of diffusion one milliliter of dye solution can be placed in each flask. Over period of one hour the colder flask will result in slower diffusion that the flask at room temperate. This experiment accurately supports that at higher temperatures molecules will diffuse faster. Diffusion in a gas can be tested by spraying a scent. However long it takes a person to smell the scent is the diffusion rate. Diffusion rate is measured in meters per second. A factor that may affect diffusion in a gas is a vent causing turbulence which may affect the rate at which the molecules…

    Another theme that was prevalent throughout the story was the struggle with communication between the couple. The communication between the characters seemed coy and often evasive. They seemed to talk around the subject instead of being upfront about how they were truly feeling. For example when the girl states “I don’t feel any way, I just know things.”(Clugston, 2010) She refuses to express how she is really feeling about her desire to keep the child. The American knows she is hesitant about the abortion, yet he continues to humor her by telling her that she doesn’t have to do it (Clugston, 2010). It almost seems as though they spend the entire conversation avoiding the subject by briefly making interjections pertaining to…

    Justice vs Charity

    Generally speaking there is a moral distinction between an act and an omission. In dealing with euthanasia, it is rational to think that the active euthanasia is further morally wrong than passive euthanasia. One would never be able to create a morally absolute rule that could address all life and death situations. Conversely, what if it is in one's most immediate interest to be relieved of their life, but they choose not to do so? Finally, how is one supposed to know whether a person wishes to live or die if that person can't communicate that thought? Using the ideals of morality and modern ethical questions, certain struggles in the field of euthanasia arise: active versus passive euthanasia, and the questions of how to deal with involuntary and non-voluntary euthanasia. Rachels sets out to contend that we are only able to answer these questions if we analyze the importance of two major factors concerning life: justice and charity.…
