9. (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. Starting/stopping the timer Size of reagent drops Mixing the reagents Counting reagent drops

Answer 1

The most probable reason for largest experimental error is size of reagent drops.

This is so because, the size of drops depend on the the dropper or another dispenser. Along with this it also depends on the person handling the apparatus. Hence, it is the prime source of error because its amount is not known accurately
