【摘要】 本文根据滴定分析的误差要求,以滴定曲线突跃范围为依据,对酸碱滴定和氧化还原滴定中,能准确滴定的条件进行了探讨。提出弱酸（碱）滴定的条件为CK≥10^-8;多元酸（碱）分步滴定的条件为Ka₁Ka₂≥10⁵,氧化还原滴定的条件为E₁^0′-E₂^0′≥0.56伏,并相应进行了有关公式的推导。更多还原

【Abstract】 On ask for errors of analysis by titratior, to be based on transitory range of titration curve, go about approach of prerequisite for exact titration in the acid-base titration and oxidation-reduction titration. Put forward prereguisite for exact titration in the weak acid （or base） is CK≥^-8, prereqnisite for stepwise titration in the poljhydric acid （or base） is Ka₁/Ka₂≥10^-5, in the oxidation-reduction is E₁⁰-E₂⁰≥0.56V. In the meantime go about deduction of these formua.更多还原
