Review about Analytical Chem

Solutions :
Concentration, calculation , Clinical Applications
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).
Compounds can be classified as either electrolytes or nonelectrolytes.
Electrolytes are solutes that form solutions
that conduct electricity.
At this point we will restrict ourselves to compounds in Aqueous solutions.
Compounds are electrolytes if their aqueous solutions conduct electricity.
Compounds are nonelectrolytes if their aqueous solutions do not conduct electricity.

Question : How to test a solution if Electrolyte or Not?

Most household aqueous solutions, such as fruit juices and cleaning solutions, contain electrolytes. The conductivity of a solution is easily tested with a simple conductivity apparatus (Figure 4) or an ohmmeter. This evidence also provides a diagnostic test to determine the class of a solute electrolyte or nonelectrolyte. This very broad classification of compounds into electrolyte and nonelectrolyte categories .
