  • Autoionization
    A process where identical molecules interact to produce ions, commonly observed in pure water forming hydronium and hydroxide ions.
  • Self-Ionization
    A phenomenon where molecules of the same substance react to generate ions, as seen when water forms hydronium and hydroxide.
  • Aqueous Solution
    A mixture where water acts as the solvent, allowing substances or ions to disperse uniformly throughout.
  • Hydronium Ion
    A positively charged species formed when a water molecule gains a proton, represented as H3O+.
  • Hydroxide Ion
    A negatively charged species resulting from a water molecule losing a proton, symbolized as OH-.
  • Acid
    A substance or particle capable of donating a proton (H+) to another species in a chemical reaction.
  • Base
    A substance or particle capable of accepting a proton (H+) from another species during a reaction.
  • Ion Product of Water
    A constant (Kw) representing the product of hydronium and hydroxide ion concentrations in water at equilibrium.
  • Kw
    A symbol for the equilibrium constant of water's autoionization, calculated as [H3O+][OH-].
  • Equilibrium Constant
    A value expressing the ratio of product to reactant concentrations at equilibrium for a reversible reaction.
  • Temperature Dependence
    A property where the value of a constant, such as Kw, changes as the temperature of the system varies.
  • 25 Degrees Celsius
    A standard reference temperature used for calculations involving Kw, where its value is 1.0 x 10^-14.
  • H+
    A proton, often used interchangeably with hydronium ion in aqueous solutions, representing acidity.
