Isotonic

solute and placed them in beakers full of a different solute. Through this experiment, I saw what happens when the solution becomes hypertonic, hypotonic, and isotonic. My hypothesis was that bag A would shrink because the water would leave the bag to go to the higher concentration. Bag B would stay the same because it would be isotonic. Bag C and D would swell because water would rush into the cell where…

which represented the conditions of normal fluid. For the hypotonic subjects, she ingested 854mL of water within 10 minutes which represented the dilution of bodily fluids by seeing the urine became clear and clear each time. For isotonic subjects, who consumed 1120mL of isotonic saline (0.9% NaCl), shown the importance of sodium related to normal body composition. For alkalosis subject, who consumed 100mL of sodium…

Method: In this experiment each group received 2 chicken eggs whose shells have been dissolved off. This gave us a differentially permeable membrane so that we can observe osmosis and what happens when the membrane is presented with different solutions. Since we did not know the concentration of the egg, we had to assume that it equaled the concentration of the membrane. We then had the ability to determine the concentration based off the assumption and the rate of osmosis. We used 5…

chart rather than a graph while recording our information telling the mass of the model cell before the experiment, what solution the cell was put into, what went into the solution, the mass of the cell after the experiment, and if the solution is isotonic, hypotonic, or…

This process allows small molecules like water and carbon dioxide to cross the Plasma Membrane. (Movement of dense areas to less dense areas.) -Osmosis: The process were small enough molecules such as water pass freely through the membranes. -Isotonic: Isotonic is the term used to identify when the osmotic concentration of two solution are equal. -Hypertonic: When solutions have unequal osmotic concentrations,the solution with the higher osmotic concentration is referred as the…

the solvent. A point reaches whereby the pressure on the outwards side of the tubing equal to the force driving the water out of the tube. At this point, no more osmosis occurs in the bag (Wisniak, 2013). Bag B stimulates a cell whose contents are isotonic to its surrounding environment. This situation arises because the concentration of the bag contents is 1% sucrose concentration that resembles the solute concentration on the outside. There is no concentration gradient created, and thus no…

A special case of diffusion is known to be osmosis, which is known to be the diffusion of water through a water allowing or permeable membrane. Only water should be able to move through most oftenly. Therefore, the diffusion of one or more other substances along with water should not come in, such as solutes. An everyday example of osmosis is from the result of proned fingers. The bathtub that the person is showering is less concentrated in comparison with your body, thus, it is using osmosis to…

2.2.3. Stability of econazole nitrate nanosuspensions All the prepared econazole nitrate formulations were dispersed in isotonic buffer pH 7.4 and measured for their particle size, polydispersity index (PDI) and zeta potential values during 6 months of storage at room temperature using time intervals of 0, 1, 2, 3, 9, 12, 19, 33, 62, 92, 122, 152 and 182 days. On the other…

We determined that Vial number one was the cloudiest, and was a darker red, this was our hypotonic solution. Vial number two was decidedly less cloudy, and a slightly less deep red, this was our isotonic solution. Vial number three was very clear and the color did not change, we were able to read writing on our notebook page through the sample, this was our hypertonic solution. In the elodea plant portion of the experiment, we noticed that the…

a solution with high sucrose content, the amount of sucrose in the sweet potatoes increases because the solutes enters a cell with higher solute potential than that of the surrounding environment. When the net osmosis rate is zero the solution is isotonic because equal amounts of solute is present in the cell and the surrounding environment causing no net movement. After the experiment, the concentrations of the unknown solution was found through reviewing the mass change and water potential…
