题型:多项选择题

某同学利用下图装置,用0.1000mol/L的氢氧化钾溶液测定某未知浓度的盐酸溶液的物质的量浓度,,其操作可分解为如下几步:

A.用标准溶液润洗滴定管2~3次

B.取标准KOH溶液注入碱式滴定管至刻度0以上2~3cm

C.把盛有标准溶液的碱式滴定管固定好,调节滴定管尖嘴使之充满溶液

D.调节液面至0或0以下刻度,记下读数E. 移取20.00mL待测盐酸溶液注入洁净的锥形瓶,并加入2~3滴酚酞

F. 把锥形瓶放在滴定管的下面,用标准KOH溶液滴定至终点,并记下滴定管液面的刻度读数。

G.把锥形瓶里的溶液倒掉,用蒸馏水把锥形瓶洗涤干净。按上述操作重复一次,并记下滴定前后液面刻度的读数。

就此实验完成填空:

(1)上图所示是              常用的仪器,(填实验名称)。图中A是                  (填仪器名称)

(2)判断到达滴定终点的实验现象是:___                 ____

              (填“偏高”、 “ 偏低”或“无影响”)。

(4)重复做该实验4次。所得实验数据如下表:

实验次数c(KOH)/mol·L-1B中起点刻度B中终点刻度V(HCl)/ml
10.1000024.9525.00
20.1000024.9625.00
30.1000024.5025.00
