Sulphate solution

stays there. Lipophilic substances (oil loving) attract the oily deposits. Surfactants are used to get rid of them. Through the use of aligning lipophilic and hydrophilic ends, it is able to take the lipids off the exterior. Foaming – Surfactant solutions can foam, as the air in liquids are trapped in the surfactant molecules. Foam is often desirable among consumers for cosmetics, so it is a key feature of surfactants. Emulsification –A lot of cosmetic products want to add oily materials to it in

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

content. For example: Container 1: 1 teaspoon of salt Container 2: 2 teaspoons of salt Container 3: 3 teaspoons of salt Container 4: 4 teaspoons of salt Container 5: 5 teaspoons of salt • Add the salt solutions to each of the containers and start the timer for 1-3 hours • Leave the solution to sit until the time is up. • When the time is up remove the potatoes from the containers one by one and measure the potatoes using the ruler and then record the results for each potato. 12. Precautions:

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

The hypothesis was not supported because the higher the concentration of NaCl solution, the lower the rate of osmosis as the water ions are attracted to the NaCl ions against the concentration gradient. As shown in table 1.0 the mass of the egg changes each time it is placed in a certain concentrated solution. The reason for this change in mass is the process of osmosis through the egg’s semi-permeable membrane. The water within the egg cell’s vacuole can expand or shrink depending on the amount

increased ECF’s absorbance in the three hypotonic solutions show that more light was absorbed - an indicator of a ruptured red blood cell. Although the 50mM solution produced a lower absorbance than the 100mM solution when the expected amount of the former should have been higher than the latter, the hypotonic solution still has a larger absorbance than the isotonic solution. It is worth noting that the hypotonic environments produced the clearest red solutions. In all three hypotonic environments, high

isotonic solution in cells, a solution in which the concentration of dissolved substances in the solution is the same as the concentration of dissolved substances inside a cell hypertonic solution in cells, a solution in which the concentration of dissolved substances outside the cell is higher than the concentration inside the cell; causes a cell to shrink as water leaves the cell hypotonic solution in cells, a solution in which the concentration of dissolved substances is lower in the solution outside

the same, cell volume stays constant. When erythrocytes are placed in a hypotonic solution (a solution with lower concentration than the cell), water moves into the red blood cell, causing it to swell, to increase its volume and eventually burst ( haemolysis). When erythrocytes are

Important equations: Molarity = moles of solute / liters of solution E = hν = hc/λ Elight = hνlight = hc/λlight = ΔE = EUO – EOO Objective: We will be using various combinations of distilled water, hydrogen peroxide, malonic acid, ascorbic acid (Vitamin C), acetic acid (Vinegar), starch solution, laundry detergent, iodine tincture, manganese sulfate, and sulfamic acid to produce multiple pairs of solutions labeled Solution A and Solution B. The goal is to either observe the process of fluorescence

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
