缓冲容量的新概念

缓冲容量的新概念 THE NEW CONCEPT OF BUFFER CAPACITY 孟凡昌 Meng Fanchang 1 first-author 武汉大学化学系 武汉大学化学系 Department of Chemistry,Wuhan University Department of Chemistry,Wuhan University 提出了缓冲容量的新概念，推导了它的数学表达式，建立了具有应用价值的计算方法，并在数学概念、物理意义以及实际应用上与缓冲指数进行了比较，澄清了两者间的混淆．本文还将缓冲容量的概念推广至多元酸，建立了定量计算方法． The new concept of buffer capacity a has been advanced.where △pH is buffer range, is mean buffer index, △C is the moles of acid or alkali that hasadded into the buffer in the range of △pH. The calculation and application of buffer capacityin mono and multibasic acids are stated and the buffer capacity arc compared with buffer index in math concept, physical sence and chemical applications. 缓冲容量 缓冲指数 缓冲溶液 buffer capacity buffer index buffer solution O645 1994-04-01 2021-04-01 4
