量筒的使用

1. 怎样选择量简?

 

  量筒是量取液体体积的仪器。规格以所能量度的最大容量(ml)表示,常用的有10 ml、25ml、50 ml、100 ml、250 ml、500 ml、1000 ml等。外壁刻度都是以 ml为单位,10 ml量简每小格表示0.2 ml,而50 ml量筒每小格表示1ml。可见量筒越大,管径越粗,其精确度越小,由视线的偏差所造成的读数误差也越大。所以,实验中应根据所取溶液的体积,尽量选用能一次量取的最小规格的量筒。分次量取也能引起误差。如量取70ml液体,应选用 100ml量筒。

 

2. 怎样把液体注入量筒?

 

 

 

  向量筒里注入液体时,应用左手拿住量筒,使量筒略倾斜,右手拿试剂瓶,使瓶口紧挨着量筒口,使液体缓缓流入。待注入的量比所需要的量稍少时,把量筒放平,改用胶头滴管滴加到所需要的量。

 

 

3 什么时候读出所取液体的体积数?

 注入液体后,等1~2分钟,使附着在内壁上的液体流下来,再读出刻度值。否则,读出的数值偏小。
 
4怎样读出所取液体的体积数?
 

  应把量筒放在平整的桌面上,观察刻度时,视线与量筒内液体的凹液面的最低处保持水平,再读出所取液体的体积数。否则,读数会偏高或偏低。
