Properties of Solutions

Properties of Solutions :

learning Objective :


1. Identify a mixture as a solution, a colloid, or a suspension.
2. Describe how the number of particles in a solution affects the osmotic pressure of a solution .
i.e. The size and number of solute particles in different types of mixtures play an important role in determining the properties of that mixture.
3. Isotonic , Hypotonic and Hypertonic .
4. Dialysis .


Solutions: are homogeneous mixtures of substances composed of at least one solute and one solvent.
homogeneous mixture: a uniform mixture of only one phase
solute: a substance that is dissolved in a solvent (e.g., salt, NaCl)
Solvent: the medium in which a solute is dissolved; often the liquid component of a solution (e.g., water)

Electrolytes can be further classified as strong electrolytes or weak electrolytes.
For a strong electrolyte, such as sodium chloride (NaCl), there is 100% dissociation of the solute into ions. When the electrodes from the light bulb apparatus are placed in the NaCl solution.
