Vocabulary Report

  • acid rain -

    rain that has become acidic (with a pH of less than 5.6) from mixing with sulfuric, nitric and other acids that are released into the atmosphere

  • acid -

    substance that donates hydrogen ions

  • base -

    a substance that produces hydroxide ions in solution

  • neutralization -

    the reaction of the ions that characterize acids (hydronium ions) and the ions that characterize bases (hydroxide ions) to form water molecules and a salt

  • pOH -

    the negative of the common logarithm of the hydroxide ion concentration of a solution

  • hydronium ion -

    an ion consisting of a proton combined with a molecule of water

  • hydroxide -

    the diatomic anion OH−, consisting of oxygen and hydrogen atoms, usually derived from the dissociation of a base

  • titration -

    a method to determine the concentration of a substance in solution by adding a solution of known volume and concentration unti the reaciton is completed, which is usually indicated by a change in color

  • *indicator -

    chemical compound that is added in small amounts to a solution so that the pH (acidity or alkalinity) of the solution can be determined

  • binary acid -

    an acid that does not contain oxygen, such as hydrofluoric acid

  • *neutral -

    substance that does not have the properties of an acid or a base but has an equal number of hydrogen and hydroxide ions

  • oxyacid -

    an acid that is a compund of hydrogen, oxygen and a third element, usually a nonmetal

  • *pH -

    a value that is used to express the acidity or alkalinity (basicity) of a system; each whole number on the scale indicates a tenfold change in acidity
