1. State the operational and technical definitions of a buffer. Operational definition (What does it do?): A buffer is a solution that resists changes in pH upon the addition of a small amount of strong acid or strong base. Technical definition (How do you make one?): A buffer is composed of a mixture·of a weak acid its conjugate base.

Jan 21, 2024 · A buffer is a solution that maintains the stability of a system’s pH level when adding small quantities of acids or bases. This characteristic makes buffers important in biological and chemical applications where pH stability is crucial.
1. Define : Buffer solution. 2. How will the pH of a buffer solution change if we add a small amount of water? (increase, decrease, or remain the same) 3. Consider the table given below, write a balanced chemical equation for any reaction taking place between solute particles.
Calculate the pH of a buffer solution made from equal amounts of 0.30 M hydrofluoric acid and 0.70 M sodium fluoride. \(K_a = 7.1 \times 10^{-4}\)
Buffers: All about those “common ions” IS: A buffer is a solution of a weak acid or base and its salt [which is its conjugate]. DOES: A buffer resists a change in pH. HOW IT WORKS: Since a buffer consists of both an acid or base and its conjugate, which differ by an H +, both a weak acid and a weak base are present in all buffer solutions.
