Solution

similar to salt water, slime often consists of H2O, either as a solvent or in a chemical bond. For example, “One variety of slime that can be easily made in the lab involves the addition of a saturated solution of sodium tetraborate decahydrate (Na2B4O7⦁10H2O), commonly known as borax, to a solution of glue and water” (Rohrig 3). Borax is commonly used…

increase. The qualitative observations show the flexibility of each potato before and after the incubation. The initial observations for the potato slivers were slightly stiff and high in flexibility. After leaving the 10 mL sucrose concentration solution for 45 minutes, the results show an increase in appearance, and flexibility of each individual potato. The qualitative observations from the initial results show that the potato cells have a flavescent colour with rigid texture. Also, the…

uction The point of this experiment is to examine the result of altering the concentration of sucrose on the rate of osmosis in cylinders of potatoes. This would occur by using like sizes and lengths of potato cylinders and applying them into varying concentrations of sucrose (1%, 5%, 10%, 15%, and 30%) in test tubes then assessing the change in mass of the potato cylinders after. Sustaining all variables unaffected such as the pH, same size, and a constant temperature. Hypothesis: I predict if…

damage. Another example of osmosis would be kidney dialysis. Kidney dialysis is for individual who undergo kidney diseases. This process involved the dialyzer to remove the waste from one’s blood through a membrane that dialyzes and passes into a solution tank. Due to the red blood cells being large in size, they ultimately cannot go through the membrane thus are retained within the blood. By osmosis, waste materials are continuously removed from the blood. On the other hand, diffusion occurs…

The variable that is manipulated, or the independent variable, is the egg. The variable that is controlled, or the dependent variable, is the liquid (the vinegar, corn syrup, and distilled water) in the cup. Before the vinegar was added to the solution, the cup’s mass was taken into account and subtracted from the mass of the egg in the cup in order to find the egg’s mass in grams.…

mixture with a high viscosity. It was deemed soluble as the mixture also produced heat- an exothermic reaction. The results between the cyclohexene and the sulfuric acid were possible due to the attraction forces between a positive hydrogen ion (in solution) and a negative oxygen ion in the sulfuric acid- a carbon from the double bond (alkene) attaches to the oxygen atom (sulfuric acid). This type of interaction is called an electrophilic addition reaction (Clark, 2017). Therefore, cyclohexyl…

Emulsions are two-phase systems, a mixture of two or more liquids that are normally immiscible. There are two phases in the system, in which one is the continuous phase and the other one is the dispersed phase. Types of emulsions [38] Oil in water (o/w): in which oil is the dispersed phase and water is the continuous phase. Water in oil (w/o): in which water is the dispersed phase and oil is the continuous phase. Emulsions have a cloudy or opaque appearance because particles scatter light…

The hypothesis that if sucrose concentration is placed in one of the model cells then the rate of osmosis will increase was supported by the data in this study. To start with, the tap water without any sucrose concentration (M) started at 4.87g and ended with almost the exact same mass after 60 minutes had passed. On the other hand, when 1.20 M of Sucrose Concentration was emerged in water for 60 minutes and pulled out, its mass went from 6.48g to 9.03g.. Osmosis is the net flow of water…

difference in salt and other particles in solution and in their cell bodies. The salinity and osmolality in an environment triggers a series of regulatory responses in the organism to maintain equilibrium. The equilibrium is essential to its cell’s life and ultimately the life of the organism. The response to maintain such equilibrium is an osmotic regulation, the regulation of the solutes in solution and the cell bodies. When a cell is in an aquatic solution, water, ions, salts, and other…

The primary purpose of this experiment was to determine the concentration of solutions of copper (II) sulfate using visible spectrophotometry and Beer’s law. In this experiment, we used Beer’s law, which states that absorbance, i.e. the amount of light absorbed by a solution, is equal to the molar absorptivity of a compound, times the path length of the cuvette, times the concentration of the solution. First, we measured the absorbance of a cuvette filled with water, then calibrated the…
