In a variety of the inorganic chemistry teaching materials and related references that the composition to give the strongest buffer capacity at pH=pKa? is not described concisely. We proposed amendment description for buffer capacity in the book written by teaching and research office of Inorganic Chemistry at Dalian University of Technology. The description is based on the distribution curve slope when buffer solution pH as close as possible to pKa?.

Key words: Inorganic chemistry, Buffer solution, Buffer capacity
