  • Henderson Hasselbalch Equation
    Mathematical formula relating pH, pKa, and the ratio of conjugate base to conjugate acid concentrations in weak acid solutions.
  • pH
    Numerical measure of hydrogen ion concentration, indicating the acidity or basicity of a solution.
  • pKa
    Logarithmic value representing the strength of an acid; lower values correspond to stronger acids.
  • Weak Acid
    Substance that only partially dissociates in solution, resulting in incomplete breakdown into ions.
  • Strong Acid
    Substance that fully dissociates in solution, producing maximum hydrogen ion concentration.
  • Conjugate Base
    Species formed when an acid loses a hydrogen ion; participates in equilibrium with its conjugate acid.
  • Conjugate Acid
    Species formed when a base gains a hydrogen ion; exists in equilibrium with its conjugate base.
  • Acid Dissociation
    Process by which an acid separates into its conjugate base and hydrogen ion in solution.
  • Equilibrium
    State in which the concentrations of reactants and products remain constant over time in a chemical reaction.
  • Hydrogen Ion
    Positively charged particle released by acids, central to determining solution acidity.
  • Logarithm
    Mathematical function used in the equation to relate concentration ratios to pH.
  • Acid-Base Equilibria
    Balance between acids and bases in solution, crucial for understanding biological systems.
  • Biological Acid
    Acid commonly found in living systems, typically weak and important for biochemical processes.
