Therefore, we averaged all the times of the reaction out to conclude with 2 minutes and 4 seconds as our final time. -Analysis Questions:1. Would you expect all members of the same group to calculate the same time?No, I would not expect all members in the same group to calculate the same time (precisely), but I would expect them all to contain similar times that are not too far apart since they should start at the same time. Furthermore, varying times would depend on how each individual perceives and reasons with the length of a chemical reaction. 2. Would you expect all groups to calculate the same average group time?No, I would not expect all groups to have the same exact time, but like the previous answer, I would expect them to have times that are approximate and slightly close to each other because baking soda times do not react consistently, but instead varies from time to time. Error Sources:One of the many possible reasons why the data might be imperfect maybe because of the baking soda being exposed to air for too long. Baking soda tends to deactivate by contact with airover time (that is the reason why it is kept in the fridge). If it has been open for a while, it definitely will be less than optimally reactive. Another possible explanation for imperfect data might be the sun and placement of the experiment. The sun is known to catalyze this acid-base reaction quicker than the shade or even the indoors. Our group set the plastic Ziploc bag in the shade, which could possibly extend our times, thus, shifting the results.
