2.8: acids

binary vs. nonbinary acids

  • binary acid: a compound in which hydrogen is bonded to a different nonmetal (not oxygen)
  • naming binary acids   * start with prefix “hydro-”   * change ending of other element to “-ic”   * add “acid” to the end     * eg. HCl = hydrochloric acid
  • nonbinary acid: a compound in which hydrogen is bonded to a polyatomic ion
  • naming nonbinary acids   * do not add the prefix “hydro-” (that is specific to binary acids)   * determine the name of the polyatomic anion on the acid; if the anion ends in:   * “-ate”: change the ending of the anion to “-ic”   * “-ite”: change the ending of teh anion to “-ous)   * end the name with “acid”   * exceptions: phosphorous acid, sulfuric acid
