Types of Buffer Solutions Acidic buffer solutions : An acidic buffer solution is simply one which has a pH less than 7 Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt A common example would be a mixture of acetic acid and sodium acetate in solution
What is a buffer solution?
A buffer (or buffered) solution is one that resists a change in its pH when H + or OH – ions are added or removed owing to some other reaction taking place in the same solution. Buffers do so by being composed of certain pairs of solutes: either a weak acid plus its conjugate base or a weak base plus its conjugate acid.
What is an example of a buffer?
Buffers do so by being composed of certain pairs of solutes: either a weak acid plus its conjugate base or a weak base plus its conjugate acid. For example, a buffer can be composed of dissolved acetic acid (HC2H3O2, a weak acid) and sodium acetate ( NaC2H3O2). Sodium acetate is a salt that dissociates into sodium ions and acetate ions in solution.
How do you make a buffer?
Perhaps the simplest way to make a buffer, however, is to prepare a solution that contains an appropriate conjugate weak acid and weak base, measure its pH, and then adjust the pH to the desired value by adding small portions of either a strong acid or a strong base.
Can a multiprotic weak acid be used to prepare a buffer?
We can use a multiprotic weak acid to prepare buffers at as many different pH’s as there are acidic protons, with the Henderson–Hasselbalch equation applying in each case. For example, for malonic acid (p Ka1 = 2.85 and p Ka2 = 5.70) we can prepare buffers with pH values of where H 2 M, HM – and M 2– are malonic acid’s different acid–base forms.
