Practical note: the base/acid ratio can be entered in moles/moles or in molarity/molarity, whichever is easier and more accessible since the volume is common to both base and acid 2. Some Practical Simple Stuff a. A buffer pH depends on: 1. pKa which depends on Ka (weak acid strength) 2. Base/acid ratio b. Common Ion Effect with Weak Acids and Bases. Adding a common ion prevents the weak acid or weak base from ionizing as much as it would without the added common ion. The common ion effect suppresses the ionization of a weak acid by adding more of an ion that is a product of this equilibrium. no effect The NaCl has no common ions to the Be(OH) 2 and +nor the Cl-forms any precipitates with either of the ions from Be(OH) .

A POGIL laboratory is one in which students, in advance of any classroom work on underlying principles, work in groups to conduct experiments, rather than exercises that verify previously taught principles. Prior to the beginning of any laboratory work the instructor poses a focus question (What factors affect the solubility of ions? Common Ion Effect Introduction The common-ion effect is used to describe the effect on an equilibrium involving a substance that adds an ion that is a part of the equilibrium. Adding a common ion prevents the weak acid or weak base from ionizing as much as it would without the added common ion.

Adding a common ion prevents the weak acid or weak base from ionizing as much as it would without the added common ion. Common Ion effect The shift in equilibrium caused by the addition of a substance having an ion in common with the equilibrium mixture. Adding a common ion suppresses the ionization of a weak acid or a weak base. The source of the common ion is typically provided by adding a strong acid, a strong base or a soluble salt to the equilibrium

The Common Ion Effect and Buffer Solutions The general expression for the ionization of a weak monoproticacid is: The generalized ionization constant expression for a weak acid is: HA →← H ++A− [ ][ ] [ ] K H A a HA = + − [ ] [ ] H K [ ] HA A + acid a − salt = × 8 The Common Ion Effect and Buffer Solutions Simple rearrangement of this equation and application of algebra yields the

  • equilibrium constants. will be for its conjugate base, and vice versa. Conjugate bases of weak acids are true bases. For example, the acetate ion (often abbreviated OAc–), which is the conjugate base of acetic acid (often abbreviated HOAc), can make a basic solution as a result of its base hydrolysis.
