isotonic solution do not experience osmosis. When the cell is hypotonic it has a lower concentration of solutes so water will move out of the cell. When the cell is hypertonic‚ it will have a higher concentration of solutes and water will move into the cell to attempt to reach an isotonic state. The primary purpose of this exercise is to measure the rate and direction of osmosis under different concentrations. The greater the concentration of the solute (sucrose) the faster the solution (water)

Business Case Analysis What is a Business Case? A business case is a tool used to manage business process improvement activities from inception through implementation. A business case is a document that identifies functional alternatives and presents economical and technical arguments for carrying out alternatives over the life-cycle to achieve stated business objectives or imperatives. Each business case will look different depending on its application. However‚ essential ingredients remain

bag. They then rubbed the other end of the bag to open it up and then are able to fill the bag with solution. The next step of the lab was to test for the presence of glucose in a 15% glucose and 1% starch. Then they took the 15% glucose and 1% starch and took 15 mL and placed them in enclosed bags. Jaydon‚ Jacob and Tyler then tie off the bag leaving room for expandable contents in the solution. Then they took distilled water and filled it with 250 mL beaker or one other option includes filling

specific solutes to and from the cell. This implies that the membrane to most cells is selectively permeable or has a differential permeability to different solutes. Both the internal and the external environment to the cell are composed an aqueous solution that is made of dissolved organic and inorganic substances. The gradual or spontaneous movement of these substances in and out the cell are guided by a mechanism called diffusion. This is a movement by molecules to a region of lower concentration

cautious when handing the precipitate as the solid separated into smaller sup unit which increased the surface area enabling the photodecomposition of the precipitate to occur more dramatically. We also added our precipitating agent to the supernatant solution too quickly‚ making all the chlorine unable to bond with the Ag+ as other‚ smaller ions co-precipitate instead. The precipitate may not have undergone a complete reaction as our test for more precipitate was not as thorough as it could have

SOLVENT EXTRACTION Solvent extraction‚ also known as liquid extraction and partitioning‚ is a method to separate compounds based on their relative solubility in two different immiscible liquid‚ usually water and organic solvent. It is an extraction from one liquid phase to another liquid phrase. Liquid extraction is a basic technique in chemical laboratories‚ where it is performed using a separator funnel. This type of process is commonly performed after a chemical reaction as part of the work-up

To determine the effect osmotic pressure might have on cellular membranes‚ specifically when beet slices are placed in NaCl solutions of varying concentrations. 2. Hypothesis: The osmolarity will directly increase with increasing NaCl concentrations. 3. Control = Distilled Water – this was present in all solutions 4. The independent variable – salinity of the 6 solutions; while predetermined‚ the NaCl concentrations varied from 0% to 15%. The dependent variable – beet osmolarity; this lab’s focus
