Summary and Introduction

Solution Composition

Concentrated  -  A solution of high concentration.
Concentration  -  The amount of solute dissolved in a given amount of solvent.
Dilute  -  A solution of low concentration or the process of lowering the concentration of a solution by the addition of solvent.
Dilution  -  The decrease of the concentration of a solution by the addition of more solvent.
Equimolar  -  Having the same molarity.
Mass Percent  -  The number of grams of solute divided by the number of grams of solution multiplied by 100%.
Molar Equivalent  -  The number of molar equivalents depends on the reaction of interest. For an acid-base reaction the number of equivalents is the number of moles of acid or base needed to fully neutralize the solute of interest. Sulfuric acid is a diprotic acid, therefore, 1 mole of sulfuric acid is 2 molar equivalents. For a redox reaction, the number of molar equivalents is the number of moles of electrons one mole of the solute can either donate or accept in the particular redox reaction of interest.
Molality  -  The number of moles of solute divided by the number of kilograms of solvent.
Molarity  -  The number of moles of solute divided by the number of liters of solution.
Mole Fraction  -  The number of moles of solute divided by the total number of moles in solution.
Normality  -  The number of molar equivalents of solute divided by the number of liters of solution.
Solute  -  A minor component of a solution.
Solution  -  A homogeneous mixture.
Solvent  -  The major component of a solution.
