Abstract

The buffering capacity of solutions of KH2PO4 and NaHCO3 increases with their concentration, the behaviour being describable by mathematical expressions. Solutions of KH2PO4 prepared from tap water exhibit a buffering capacity higher by an order of magnitude than those prepared from distilled water. However, there is no difference between the buffering capacities of solutions of NaHCO3 prepared from tap and distilled water. Urea and NH4NO3 have almost no effect on the buffering capacities of solutions.

摘要

磷酸二氢钾（KH₂PO₄）和碳酸氢钠（NaHCO₃）溶液的缓冲能力随其浓度增加而增强，这种行为可用数学表达式描述。用自来水配制的磷酸二氢钾溶液的缓冲能力比用蒸馏水配制的溶液高一个数量级。然而，用自来水和蒸馏水配制的碳酸氢钠溶液的缓冲能力没有差异。尿素和硝酸铵（NH₄NO₃）对溶液的缓冲能力几乎没有影响。
