【摘要】 研究了当pKa一定时,总浓度一定的共轭酸碱所配制的不同pH值的缓冲溶液在给定的缓冲范围下的缓冲容量,得出结论:当总浓度和pKa一定时,若规定了缓冲范围ΔpH,不同pH值的缓冲溶液对酸、碱的缓冲容量是不相等的,在pH=pKa时,缓冲溶液分别对酸或碱的缓冲容量并不一定都是最大的。更多还原

【Abstract】 The buffer capacity of buffer solutions with different pH made by the same conjugate acid-base and the same total concentration was studied in the given ΔpH buffer range.The results obtained showed that the buffer capacity of buffer solutions to acid or base were not all maximum at pH=pKa if buffer solutions with different pH made by the same conjugate acid-base had an equal total concentration and buffer ranges ΔpH were proposed更多还原
