如果M与A进行滴定反应，称主反应 M+A≌MA 将HA和M同时引入含X的体系，则 CA=[H3A]+[H2A]+[HA]+[A]+[MA] CM [M]+[MX]+[MX2]+[MX3][MX4]+[MA] 将除产物MA以外的平衡浓度的总和记为[A']和[M'] [A]=[HA]+H2A]+[HA]+[A CA [A']+[MA] [M']=M+[MX]+[MX2]+[MX]+[MX4] CM=[M']+[MA] [A],[M]被称为总平衡浓度 如果M与A进行滴定反应，称主反应 M + A MA 将H3A和M同时引入含X的体系，则 cA = [H3A] + [H2A] + [HA] + [A] + [MA] cM = [M] + [MX] + [MX2] + [MX3] + [MX4] + [MA] 将除产物MA以外的平衡浓度的总和记为[A′]和[M′] [A′] = [H3A] + [H2A] + [HA] + [A] cA = [A′] + [MA] [M′] = [M] + [MX] + [MX2] + [MX3] + [MX4] cM = [M′] + [MA] [A′], [M′]被称为总平衡浓度
