Weak Bases and Ionization Constants

Flashcards covering key terminology and concepts related to weak bases and their ionization constants.

Weak Base

A base that partially ionizes in solution.

Kb

Base ionization constant, used to express the strength of a weak base.

NH3 (aq)

Ammonia in aqueous solution, a common weak base.

Ionization Constant

A value that indicates the extent to which an acid or base ionizes in solution.

pOH

The negative logarithm of the hydroxide ion concentration, used to calculate the acidity or basicity of a solution.

Equilibrium Concentration

The concentration of reactants and products in a solution when a chemical reaction reaches a state of balance.

Conjugate Acid-Base Pair

A pair of substances related by the transfer of a proton (H+).

Ka

Acid dissociation constant, used to express the strength of a weak acid.

Kw

The ion product constant of water, equal to [H+][OH-] at 25°C.

pH Calculation

Determining the pH of a solution using the concentration of hydrogen ions.

Concentration (M)

Molarity, a measure of the amount of solute in a given volume of solution.

Aqueous Solution

A solution in which the solvent is water.
