Solution A homogeneous mixture of two or more substances with each substance retaining its own chemical identity. Solute – substance being dissolved. Solvent – liquid water. General Properties of a Solution 1. Contains 2 or more components. 2. Has variable composition. 3. Properties change as the ratio of solute to solvent is changed. 4. Dissolved solutes are present as individual particles. 5. Solutes remain uniformly distributed and will not settle out with time. 6. Solute

from high to low concentration. Osmosis is the movement of water from low to high concentration. Both refer to movement in/out of a cell‚ but osmosis refers specifically to water. 2. Isotonic‚ hypertonic‚ and hypotonic all refer to the comparison of concentrations of solutes in verses out of the cell. Isotonic is when the concentration in the cell is the same as the concentration outside of the cell. Hypertonic is when the concentration outside of the cell is greater than inside. And hypotonic

tonicity that one solution can have relative to another. Those are hypertonic‚ hypotonic‚ and isotonic. Hypertonic solutions(more dissolved solute)-the solution with a higher concentration of a solute. Water leaves the cell and the cell shrinks. Hypotonoic solution(less dissolved solute)-the solution with the lower solute concentration. Water molecules enter the cell and the cell becomes larger. Isotonic solution(same amount of dissolved solute)-the solution of equal solute concentration.

Also‚ understanding of which way substances will move passively through a deferentially permeable membrane depending on the concentration differences. We used PhysioEx software to examine diffusion. In these experiments we used different sized membranes as well as NaCl‚ urea‚ glucose‚ albumin‚ powdered charcoal‚ and KCl. The step by step process was used by the software so that we could see the different kinds
