    15.1 : Bronsted-Lowry Acids and Bases

    The acid-base reaction class has been studied for quite some time. In 1680, Robert Boyle reported traits of acid solutions that included their ability to ...

    15.2 : Acid/Base Strengths and Dissociation Constants

    The relative strength of an acid or base is the extent to which it ionizes when dissolved in water. If the ionization reaction is essentially complete, ...

    15.3 : Water: A Bronsted-Lowry Acid and Base

    The reaction between a Brønsted-Lowry acid and water is called acid ionization. For example, when hydrogen fluoride dissolves in water and ionizes, ...

    15.6 : Strong Acid and Base Solutions

    A strong acid is a compound that dissociates completely in an aqueous solution and produces a concentration of hydronium ions equal to the initial ...

    15.7 : Weak Acid Solutions04:02

    15.7 : Weak Acid Solutions

    Few compounds act as strong acids. A far greater number of compounds behave as weak acids and only partially react with water, leaving a large majority of ...

    15.8 : Weak Base Solutions

    Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially and ...
