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
