egg submerged in maple syrup), were recorded. Then, the egg was removed from its solution, rinsed in tap water, and placed in a glass. Once in the glass dish, the dish was placed on a triple beam balance, and the final mass was measured and recorded. 29 Minutes after being submerged in tap water, observations pertaining to egg A (the egg submerged in tap water) were recorded, and the egg was removed from its solution, and placed in a glass dish, to be placed on the triple-beam balance. Once on…

hypotonic osmosis occurs. The concentration of the solution outside of the potato cells was higher than the concentration inside the potato. This caused the transportation of the solution towards the lower gradient. The solutions 0.40mol/L, 0.60 mol/L, 0.80 mol/L, 1.0mol/L lost mass after diffusion. This is due to there being a higher concentration inside of the potato cells than in the glucose solution. The transport went to the glucose solution outside of the potato, which made it…

osmosis, water moves down its concentration gradient from a low solute concentration to a solution with a high solute concentration. In addition, an increase in the mass of the potatoes occurs because the highly concentrated solutions were hypertonic. Potatoes with the greater increase tend to be the sweet potatoes because the potatoes already have sucrose embedded in the substance. When placed in a solution with high sucrose content, the amount of sucrose in the sweet potatoes increases because…

in the cell; to maintain the cell’s homeostasis.Within the experiment two types of solutions were present: Hypotonic and Hypertonic. Hypotonic is when the higher concentration lies in the actual cell than in the fluid surrounding it, which allows the molecules to diffuse into the cell causing the cell to swell. Hypertonic solutions however, are when cells…

THE EFFECTS OF OSMOSIS INTRODUCTION Osmosis is the process where molecules of a solvent are prone to pass through a semi-permeable membrane, going from a less concentrated solution to a higher concentrated solution. Doing this equalizes the concentrations on both sides of the membrane. Our question throughout the experiment was; What effects do the different concentrations of sucrose have on the rate of osmosis? The hypothesis was; If the solute concentrations do effect the rate of osmosis,…

letting the potatoes sit for a few days. The potato in the freshwater solution was soft and sticky, it could be easily squished it also had a bad scent because the potato had gone bad. However, the potato in the saltwater solution was firm and had become more narrow than before, it did not have a scent like the freshwater potato did. The solution that caused the potato to change the most in circumference and mass, was the saltwater solution. In the data table the potato in the fresh water had a…

The purpose of this experiment is to demonstrate the molar mass by using the freezing points of the two solutions. Colligative properties were used in calculations during this experiment to discover the molar mass of an unknown solute. These properties are subsequently applied to solutions depending on the amount of particles of the solute and the solvent inside the solution. In this lab, we focus on the freezing point depression, which can be seen when a pure solvent is added to or mixed with a…

one of the deficiencies. Develop practical actions that can output many results by reducing, abolishing or functioning around each of the top obstacles inorder to get the job done. The after affect will allow the workers to embark on looking for a solution to the other issues at hand. Unfortunately, stakeholders find themselves in conflict with one another when working on joint project(s). For instance, think about establishing…

(II) in simulated wastewater by emulsion liquid membrane technology (ELM). It has been transported of nickel ion (II) and Cadmium (II) from aqueous solution. Which contains a single compound system and A complex system through the emulsion liquid membrane emphasis was placed on it. It was the use of the effect of the concentration of citrate buffer solution and mobile carrier and stripping phase. This parameter represents a very important factor to affect Ni(II) and Cd(II) in flux through in…

A dilution is created when two solution are mixed together to reduce the concentration, or when water is added to a solution for the same reason. Molarity is the amount of molecules that a substance contains, for example, the amount of sodium ions in water after adding 2 grams of salt or the amount of sodium chloride molecules to in 10 grams of salt. The reason that we need to understand the molarity of a substance is to have a more controlled experiment. When the molarity of a substance is…
