Test 1 shows the 1st test of the experiment, over a duration of 5 days.
Test 2 shows a second set of experiment with the same variables as test 1 and it was also conducted over a duration of 5 days.
3.3 Special observations
We observed that the average weight loss in eggshells is the highest in those eggshells soaked in pH 5 and pH 6. The outcome is different from our hypothesis which states that the eggshells soaked in the lower pH value solution will have a higher amount of corrosion. However, cracks as a result of corrosion, were noted in the eggshells soaked in pH 3 and pH 4 but no crack was noted in the eggshells soaked in pH 5 and pH 6.
