摘要
根据酸碱滴定至化学计量点时溶液中存在的形体写出质子条件,然后由酸碱反应和酸碱滴定的关系式直接导出酸碱滴定误差公式。此公式为精确表达式,还可以结合实际滴定体系做进一步简化处理得出近似计算式。该方法简便、直观、易于理解和掌握。
According to the forms of the acid-base titration system in stoichiometric point,the proton balance equation is written.Then the formula of the acid-bade titration error can be directly deduced from acid-base reaction and acid-base titration relationship.This formula for the exact expression is done further to the simple approximate formula with the actual titration system.The method is simple,intuitive,easy to understand and master.
