PPT-Buffers and Titrations

Dr Harris Ch 21 Suggested HW Ch 21 1 13 29 Buffers Solutions that contain both a weak acid and its conjugate base are called buffers Buffers have the unique ability to resist sharp changes in pH. Riparian buffers commonly do not have definitive boundaries and may include stream banks floodplain wetlands and grassland buffers as well as sub irrigated sites forming a transitional zone between upland and aquatic habitat FUNCTIONS OF RIPARIAN B Year 12 Chemistry. What is a buffer?. A buffer is a solution that resists changes in pH when small amounts of acid or base are added to it. There are 2 types:. Acidic. Alkaline. Acidic buffers. An acidic buffer has a pH less than 7. . Fundamental Questions for an Analytical Chemist. What is in the sample?. How much is there? . What is the elemental composition?.
