在高三实验专题复习时 ,有这样一道题 :下列实验操作所得实验结果比理论数值偏高的是 (　　 ) .Ａ .用量筒量取 8.5ｍＬ液体时 ,仰视液面读数 .Ｂ .中和滴定达到终点时 ,仰视滴定管液面读数 .Ｃ .配制一定物质的量浓度的溶液 ,定容时仰视溶液液面读数 .下面用简便的图示法进行 During the review of the senior three experimental subjects, there was such a problem: The experimental results obtained from the following experimental operations were higher than the theoretical values ​​(). A. When the measuring cylinder weighed 8.5 mL of liquid, the liquid level was read upwards. B. The neutralization titration reached At the end point, look up the burette level reading. C. Prepare a solution with a certain amount of substance, and look at the solution level reading at constant volume. The following is performed using a simple graphic method.
