Question

(4 pts) Which of the following technique aspects do you expect to lead to the largest experimental error? Explain your choice and include a description of how the measured time could be altered. 9. Starting/stopping the timer Size of reagent drops Mixing the reagents Counting reagent drops

chemistry lab question: provide a thorough answer. address all of the needed.

Answer 1

i) Starting/stopping the timer will not lead to the experimental error because it is an accurate method.

ii) The size of the reagent drops will lead to the experimental error because the lesser the drop size, the greater is the reaction time and vice-versa.

iii) Mixing the reagents will not lead to the experimental error because, during the process, one needs to mix the reagents.

iv) Counting reagent drops will lead to the largest experimental error because one drop may be small, one drop may be large, one drop maybe medium and time between the drops is such that you can't recognize exact number of drops.
