Question
indicate whether each of the following experimental “blunders” would produce a high result, a low result, or make no difference in the value obtained for the concentration of CuSO4 unknown solution.A. In the first flask, the contents are not completely dried before weighing
B. In transferring the unknown concentration to the flask, some material is left in the pipet
C. the flasks are weighed while they are still warm indicate whether each of the following experimental “blunders” would produce a high result, a low result, or make no difference in the value obtained for the concentration of CuSO4 unknown solution.

A. In the first flask, the contents are not completely dried before weighing
B. In transferring the unknown concentration to the flask, some material is left in the pipet
C. the flasks are weighed while they are still warm
Explanation / Answer
A: if content was not dried then we take less amount which actualy requires for making solution so the answer is low result is obtained
B: If some material is left in the pipete then it means we does not transfer exact amount which is required for preparing solution. In this case also low result is obtained
C: No effect because it the amount of water and content that affect change in concentration
