A logarithmic measure reflecting the hydrogen ion activity in a solution, indicating its acidity or basicity. Kw
The equilibrium constant for water's self-ionization, varying with temperature and affecting neutral solution calculations. Ionic Strength
A quantitative measure of the total concentration and charge of ions in solution, influencing activity coefficients. Activity Coefficient
A factor correcting ion concentrations for non-ideal behavior due to electrostatic interactions in solution. Solubility Product
An equilibrium constant describing the extent to which an ionic compound dissolves in solution, symbolized as Ksp. Neutral Solution
A state where hydrogen and hydroxide ion concentrations are equal, resulting in a balanced pH. Common Ion Effect
A phenomenon where the presence of an ion shared with the solute reduces its solubility in solution. Non-Common Ion Effect
An influence on solubility and ionic strength caused by ions not shared with the solute, altering equilibrium. Hydronium Ion
The predominant form of hydrogen ion in aqueous solution, central to acidity and pH calculations. Hydroxide Ion
A negatively charged ion formed in water, essential for determining basicity and pOH. Temperature Dependence
A property where equilibrium constants like Kw change with temperature, impacting pH and solubility. Saturated Solution
A solution containing the maximum amount of dissolved solute, in equilibrium with undissolved excess. Barium Hydroxide
A strong base whose dissolution and solubility are influenced by ionic strength and non-common ions. Lithium Nitrate
An ionic compound used to adjust ionic strength in solutions, affecting activity coefficients and solubility. pOH
A logarithmic measure of hydroxide ion activity, used alongside pH to describe solution basicity.
