Final Post :) due 05/07/2012 at 10:00 am

Compare and contrast Arrehnius, Bronsted Lowry, and Lewis acids and bases to each other. Focus on the definitions for each. A chart may help.

  1. The Arrhenius model says that acids always contain H+ and that bases always contain OH-.

    The Bronsted-Lowry model thinks of acids as being proton donors and proton acceptors, so bases no longer need to contain OH-, and acids donate a proton to water forming H3O+.
    :)
    Lewis acids are electron pair acceptors, and Lewis bases are electron pair donors. H+ + OH- => H20. H+ has no electrons, so when it bonds to the Oxygen, it gains an electron pair. OH- "loses" an electron pair.

  2. An Arrhenius acid is a compound that adds hydrogen ions (H+) to a solution, while an Arrhenius base adds hydroxide ions (OH-) to a solution.

    Bronsted-Lowry acid is identical to an Arrhenius acid for it donates a proton or hydrogen ion nucleus, which is really the same thing. A Bronsted-Lowry base is a proton acceptor.

    Lewis acids are defined as electron pair acceptors, while a Lewis base is an electron pair donor.

  4. The Arrhenius acid is a chemical compound that increases the concentration of hydrogen ions, H+, in aqueous solution. (H+ or H30+ producer) The Arrhenius base is a substance that increases the concentration of hydroxide ions, OH-, in aqueous solution. (OH- producer)

    A Bronsted-Lowry acid is a molecule or ion that is a proton (H+) donor. A Bronsted-Lowry base is a molecule or ion that is a proton (H+) acceptor.

    A Lewis acid is an atom, ion, or molecule that accepts an electron pair to form a covalent bond. A Lewis base is an atom, ion, or molecule that donates an electron pair to form a covalent bond.
