What is the difference between relative concentration and precise concentration?
Relative concentration gives you a comparison of two or more solutions, telling you which has a higher concentration of some solute than the other. Precise concentration would normally be expressed in terms of moles per liter, and it tells you the actual amount of a solute that is present in a given volume of solution.
What is diffussion and osmosis?
The difference between diffusion and osmosis is that diffusion is the passive movement of particles from an area of high concentration to an area of low concentration down the concentration gradient. Particles will continue to move until dynamic equilibrium is reached, which is a state where the particles are evenly spread.Osmosis is the movement of water from a hypotonic solution (solution with less concentration) to a hypertonic solution (solution with a greater concentration of solute). Water will move to even the concentration of the two solutions to establish a state where both solutions are isotonic. ( two solutions have the same concentration).
When concentration of two solutions is the same?
Isotonic
What are solutes and solutions?
A solute is a substance that dissolves in a solvent. Like salt (solute) dissolving in water (solvent). The two together make up a solution.
What are two ways you can decrease the concentration of a solution?
Well, a solution is made of a solute dissolved into a solvent, so you could decrease the concentration either by adding more solvent ("watering it down") or removing some solute.
What does it mean when two solutions are isotonic?
When two solutions are isotonic it means that they have an equal amount of solute concentration. This state is referred to as dynamic equilibrium.
What refers to the relative solute concentration of two solutions?
molars
When comparing two solutions the solution with the greater concentration of solute is?
its called hypertonic
When two solvents are separated by a semipermeable membrane water flows from low solute concentrations to high solute concentrations. What would happen if external pressure is applied to the solution?
"Water ALWAYS follows the salt" or to put it another way, it will try to make the two sides have equal amounts of water. The water will go where there are more solute particles. Water easily passes from one side to the other by simple osmosis.

How are hypertonic and hypotonic solutions similar?
In osmosis, the hypertonic solution is one with a higher solute concentration over the semi-permeable membrane and the hypotonic solution is one with a lower solute concentration over the semi-permeable membrane. The similarities between these two is that both contain a solute and both involve water which is essential in osmosis. Also, the semi-permeable membrane plays a very important roll on how the water moves. It moves from the lower solute concentration to the higher solute concentration.
If two solutions having different osmolarities are separated by a water-permeable membrane will there be a change in the volume of the two compartments if the membrane is impermeable to solutes?
Water will flow from a region of higher concentration to lower concentration until the two osmolarities are equal if the membrane is impermeable to the solute. A change in the volume of the solution would be the result. If it is permeable then the solute will diffuse simultaneously from the higher solution to the lower solution until equilibrium is reached. The volume will not change in this case.

When comparing two solutions the solution with greater concentration is?
It often depends. The one with more solute has a higher concentration of solute than the other. In pertaining to osmosis, the hypotonic (or hypoosmotic) solution has less solute and more water over a semi-permeable membrane where the hyperotonic (or hyperosmotic) solution has more solute and less water over a semi-permeable membrane.

What type of solution will cause water to move into a cell?
The terms associated with this phenomenon can be quite difficult to get the grasp of for some reason or another to all students. The best way I can describe this is by starting with the solution. By definition of a solution you have a solute and a solvent. The solute is the substance with the lesser concentration. ( e.g. if you have a solution of Salt Water The NaCl (table salt) is dissolved into the H2O( water) since the Salt is being dissolved it is the solute. If you have 2 solutions of salt water Solution A : 10% salt; 90% Water Solution B : 30% salt and 70% water. The two solutions are obiviouslty not equal in proprtion (if they were they would be Isotonic [ equal concentration amounts of water in both solutions]) A Hypertonic Solution Means that it has a higher concentration of solute then the solution in comparison. in this case the solution B would be hypertonic to Solution A. This because the Solute concentration is higher in B than A. Solution B is the hypotonic to solution A because it has a lower concentration of solute. Osmosis is the diffusion of water across a membrane from an area of higher concentration to an area of lower concentration so since Solution B has a lower concentration of water Solution A will pass water into it going from hypotonic to hypertonic.
How is a hypertonic solution different from a hypotonic solution?
Hypotonic solution has much less particles dissolved inside the solvent than there is in the cell floating in the mixture. A hypertonic solution has a greater concentration of particles dissolved in the solvent than inside the cell.
