The Effect of Placing Pieces of Potato in a Sucrose Solution

- The Effect of Placing Pieces of Potato in a Sucrose Solution [IMAGE]Osmosis Osmosis What is osmosis. If two solutions of different concentration are separated by a semi-permeable membrane which is permeable to the smaller solvent molecules but not to the larger solute molecules, then the solvent will tend to diffuse across the membrane from the less concentrated to the more concentrated solution. This process is called osmosis. Osmosis is of great importance in biological processes where the solvent is water....   [tags: Papers]

The average of the three trials was computed as 4.56(C/m) as shown in Table 1, however, the theoretical value was slightly lower than calculated, 4.3(C/m). This resulted in a 6.04% error as shown in Equation 5; possible causes of error could have resulted from adding too much solute or too little solvent, then the calculations would have been off given that the solution was not dilute enough....   [tags: Solvent, Solubility, Melting point, Solution]

The Extraction Procedure For Separate The Acid, Base And Neutral Components Of The Solution Into Separate Phases

- The extraction procedure was undertaken in order to separate the acid, base and neutral components of the solution into separate phases. This procedure was executed using different solvents with different polarities in order to extract the different solutes. The recrystallization procedure was undertaken in order to purify the solutes further by removing any contaminants. This was done by using hot solvent and then allowing it to cool, which causes the compound to precipitate out. This creates purified crystals that have less other associated compounds....   [tags: Solubility, Solvent, Solution, Acetic acid]

Osmosis Is A Special Case Of Diffusion

- Osmosis is a special case of diffusion. It is when the passage of water from a dilute solution moves through a semi-permeable membrane to a more concentrated solution. Selective permeability is whether solutes can cross through a membrane freely or not at all. Plant cells and animal cells differ in that plant cells have a strong cell wall and animal cells do not have cell walls. They both can undergo osmosis and both lose water, however the cell wall of plant cells prevent the cells from bursting whereas animal cells will burst because they have no cell wall....   [tags: Osmosis, Semipermeable membrane, Cell wall]
