    Study Notes

    Bronsted-Lowry Definitions

    • A Bronsted-Lowry acid is a proton donor, which means it donates an H+.
    • A Bronsted-Lowry base is a proton acceptor, which means it accepts an H+.

    Proton Explanation

    • A proton is the nucleus of a hydrogen atom, which is one proton and one electron.
    • When the electron is removed, the nucleus is left with just the proton, denoted as H+.

    Acid-Base Reaction Example

    • HCl is a Bronsted-Lowry acid, which donates a proton to water.
    • Water acts as a Bronsted-Lowry base, accepting the proton.
    • The reaction forms the hydronium ion (H3O+) and the chloride anion (Cl-).

    Conjugate Acid-Base Pairs

    • HCl and Cl- are a conjugate acid-base pair, with a one-proton difference.
    • H2O and H3O+ are another conjugate acid-base pair, also with a one-proton difference.

    Lewis Definitions

    • A Lewis acid is an electron pair acceptor.
    • A Lewis base is an electron pair donor.

    Lewis Acid-Base Reaction Example

    • Boron trifluoride (BF3) is a Lewis acid, which accepts a pair of electrons.
    • Water acts as a Lewis base, donating a pair of electrons to form a bond with BF3.
    • The reaction forms a bond between the oxygen and boron, with a +1 formal charge on the oxygen and a -1 formal charge on the boron.

    Key Points

    • The Lewis definition is more broad and can apply to acid-base reactions that don't involve H+.
    • The Bronsted-Lowry definition only applies to reactions that involve H+.
    • Both definitions can be used to describe the same reaction, but the Lewis definition is more general.
