  • Arrhenius Theory

    Acids yeild H+ ions as the only positive ion in solution. Bases yeild OH- ions as the only negative ion in solution.

  • Henderson

    Henderson wrote the equation that Hasselbalch later rewrote. It was derived from the Acid dissociation Constant equation.

  • Hasselbalch Equation

    The Hasselbalch equation is used to find the pH of buffers The Equation is pH = pKa + log ([A-]/[HA])

  • Brønsted-Lowry Theory

    Bases accept protons (H+). Acids donate protons (H+).

  • Lewis Theory

    Acids accept electrons. Bases donate electrons.
