Thiosulphate solution

There are various factors relating to molecular structure that influence paracetamol solubility in various co-solvent systems. Dissolving a solute involves breaking intermolecular forces between solvent molecules and forming intermolecular bonds between solvent and solute molecules. In part this depends on the strength of solvent intermolecular forces, which is reflected in the solvent’s viscosity. Of the co-solvents, glycerol has the greatest viscosity and hence the strongest intermolecular forces

Have you ever seen a sugar cube just magically disappear when stirred in a hot cup of tea? If yes, this is the work of solubility. Solubility is the dissolving of a substance or a solute into a liquid or a solvent. In the tea example, the sugar cube would be the solute because it is being dissolved and the tea would be solvent because it is doing the dissolving. There is much more to solubility than a solute and a solvent though, there is a certain temperature that all solvents must be to dissolve

Discussion: This lab shows ‘diffusion’ of agar cube. The agar contains high concentration of solute (phenolphthalein) and the sodium hydroxide has lower concentration of solute (phenolphthalein). So as the phenolphthalein in the agar cube diffuses out to the sodium hydroxide, which turns the color of liquid, the sodium hydroxide diffuses into the agar cube that turns the color of agar cube as well. Based on the result, the optimum size for a cell is small size as they could be. The reason why is

concentration between the solution and potato. For instance, in the graph that above shows the first one on x-axis is the highest mass of potato that spent 5 days in distilled water. On the other hand, the fourth one is the lowest mass, which represents 4M sucrose solution of potato. Moreover, the data proves my prediction, as water molecules from higher sucrose solution of potato moves out actively from the potato through semi-permeable membrane into the sucrose solution. In details, the important

Abstract Cells and molecules in the environment are constantly moving and changing, for cells to function properly there is a need for equilibrium to be met. The size of the cell and the solution outside of the cell affects the rate of diffusion and osmosis in the cell. Cells are constantly trying to reach an equilibrium with the molecules and substances around it, which is why there are such terms as: hypertonic, hypotonic and isotonic. The procedures allowed testing of whether or not surface area

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

One experiment was conducted for this lab report on osmosis and diffusion and how the concentrations effect a cell. The lab consisted of weighing 4 potato cylinders and putting them into 4 cups with different levels of sucrose solution. After incubating for two hours the potatoes were weighed again and the data was collected. The results showed two increasing, one staying the same, and one decreasing in mass. Osmosis is when water moves across cell membranes until both sides are balanced (Campbell

diffusion when it moves from higher concentration to lower concentration the experiment mainly discuss how diffusion and finding which of the substance permeated out of the membrane through testing in the experiment we tested the distilled water solution on a culture dish because we were curious to see which one of the compounds is small enough to go through to permeate through the membrane after testing of glucose chloride ions and sulfate ions showed positive on the test this indicates that

Question: What effect do different concentrations of a sugar solution have on the egg and its weight? Background Research: Osmosis is the passive transport of water across a selectively permeable membrane from an area of high concentration to an area of low concentration. Other than the concentration gradient, a factor that affects osmosis is temperature. The higher the temperature, the faster osmosis takes place. Osmosis doesn’t require energy for it to take place. However, osmosis does have a
