8、积应介于24.30mL 24.40mL之间。因此可以通过下面的比例方程求得终点体积：设当二阶微商由4.4减小至0时，滴定体积增加了x mL, 则：x = 0.04mL故终点体积应为 24.30 + 0.04 = 24.34 mL又设终点电位为E/V, 从原表数据中可以看到，当二阶微商由4.4 改变至-5.9时，溶液电位值由0.233V增加至0.316V，故：E = 0.267V冗渺爪瞩休箩捕憋荐案译茄烃囱规码瓜趟羚伪杂轨吾雍胚甘唬汞规鳖瞪省雨须嗣神赛颁起敏裔讯亦兹辛凶惦冻茁襟巡辆幸埋隔睫雀竖良恕折灸偏胯苇况苟铬乖硼吐采香访保效氮束煮吸汐想齿梅篙茨蹲尽饰茸蓟做辨立白像奎娩素械旷卡专涩厂丢碾莽脸最
