Equilibria Flashcards
Conjugate pair def?
An acid-base pair on each side of an acid-base equilibrium equation that are related to each other by the difference of a hydrogen ion.
Kw, Ionic product of water def?
The equilibrium constant for the ionisation of water at conditions
Ka, Acid dissociation constant def?
The equilibrium constant for the dissociation of a weak acid
Buffer solutions def?
A solution that minimises changes in pH when small amounts of acid or base are added
Ksp, Solubility product def?
The product of the concentrations of each ion in a saturated solution of a sparingly soluble salt at 298K, raised to the power of their relative concentrations
The common Ion effect def?
The reduction of the solubility of a dissolved salt by adding a compound that has an ion in common with the dissolved salt
Kpc, Partition coefficient def?
