Thiosulphate solution

sucrose solutions (0M, 0.2M, 0.4M, 0.6M, 0.8M, 1M) affect the mass of potato cores when in sucrose solution? Background information: Osmosis is the diffusion of water across a membrane to create an equilibrium between the levels of concentration of a solute both inside and outside the cell. In this case the solute will be sugar as the potato core will be immersed in sucrose solution. There are 3 potential states that the cell could be in depending on the type of solution: Either the solution is hypotonic

In our design, it was determined that a base following a triangular pattern made of bundles of spaghetti, would be required for a strong foundational support. Initially, we planned to use tape to hold these bundles together, however tape was not permitted. We therefore had to use glue to construct the bundles together. Every feature of the bridge was constructed using these bundles, from the triangles in the base, to the supporting poles, which held and connected all the features together. After

lab the students were able to distinguish water potential in both hypotonic and hypertonic mixtures. It was perceived that the solution with the highest sucrose concentration was the purple mixture in contrast the blue mixture was at equilibrium, it was at zero. As the lab proceed and data was collected it was observed that the dialysis tube which contained the blue solution had an equivalent amount of molarity as the water that was in the beaker, to reference zero morality or equalibrum. 4. Objective:

In the first step the benzoic acid had to be dissolved in the solvent, water, so that the impurities can separate from the benzoic acid. Next, the solution was cooled slightly to add decolorizing charcoal in order to remove the impurities. Then, the solution was heated up again for 20 minutes. Then, the solution was filtered so the charcoal wouldn’t be in the final product. Finally, when filtering with the Buchner funnel the water was cooled this was used to prevent the benzoic

Ive actually conducted an experiment where three potato strips were put into three different solution: distilled water, 10% NaCl, and 85% NaCl. The potatos were left in the solutions for fortyfive minutes. The experiment is to test different versions of osmosis. After fortyfive minutes had passed I took the potatos out of the solutions, and observed the results. The potato that was in the 10% NaCl solution was still firm, but slightly bendable. The potato strip that was in the distilled water was

How does viscosity affect the speed of a sinking marble? I did this project because I wanted to know what viscosity was.Also I wanted to know how to measure it. Viscosity is the thickness of a liquid, and also what makes a liquid flow slower or faster. For example milk and honey. Honey would be thicker than milk so the honey would flow slower than the milk. Viscosity also takes place in molecular bonds. For example, if a fluid is very viscous (like honey), it would have stronger molecular bonds

The correct theoretical empirical formula for the Hydrous Copper Sulfate solution is CuSO4 * 5H2O. From the data and results of calculation from this experiment, the empirical formula that was found during the process is CuSO4 * 5H2O. The sum of the percentage from the water, copper, and sulfate found in the solution added up to be 102%, a little over the normal 100%. From the least to greatest percentage of error, copper (Cu) with 2.291%, water (H2O) with 2.77%, and sulfate (SO4) with the greatest

solutes on the outside of the cell than the inside of the cell. Water travels out of the cell towards the outside of the cell where the less pure solution is. The cell is all shriveled up. Hypotonic- Lower concentration of solutes on the outside of the cells than the inside of the cell. Water travels toward the inside of the cell where the less pure solution is. The cell is all bloated up. Isotonic- The concentration of solutes on the outside of the cell and the concentration of solutes on the inside

For a solution to be Isotonic cells are placed in water, so they neither gain or lose water through osmosis because the concentration of solutes in the cell are equal to the solutes outside of the selectively permeable membrane. (Jarod Saucedo, 2012). Although isotonic solutions neither gain or lose water Hypertonic Solutions on the other hand loses water by osmosis and shrink, this is when osmosis uses diffusion.

An investigation to find the water potential of potato and carrot tubers in a sucrose solution, of concentration 0.00 – 0.50Mol, over a 24 hour period Interpretation Written Communication C1 From our graph it can be seen that the concentration of sucrose solution is 0.18 M at 0% change in mass for the potato and 0.355 M at 0% change in mass for the carrot. I will use these values to find the solute potential by using the calibration graph. I will work out the water potential by using the
