WebScience Chemistry Good's buffers are compounds that are useful near neutral pH. MES buffer has pKa of 6.15, MOPS has p?apKa of 7.5, and HEPPS has pKa of 8.0. Identify which Good's buffers are most effective near pH 7.0 and near pH 6.0. Not all buffers will be used. A. MOPS B. MES C. HEPPS. Good's buffers (also Good buffers) are twenty buffering agents for biochemical and biological research selected and described by Norman Good and colleagues during 1966–1980. Most of the buffers were new zwitterionic compounds prepared and tested by Good and coworkers for the first time, though … See more Good sought to identify buffering compounds which met several criteria likely to be of value in biological research. 1. pKa: Because most biological reactions take place near-neutral pH between 6 and 8, ideal buffers … See more The following table presents pKa values at 20 °C. Values change by about 0.01 per degree of temperature. Good's original 1966 paper had two older buffers (marked with italics) for … See more • Buffer solution • Britton–Robinson buffer See more
