10. Consider the following potential sources of experimental error. Predict whether these errors would produce a percent mass water that is higher (H), lower (L) or the same (S) as the theoretical percent mass water. Explain your answer. (Hint: it may be useful to consider how each of these errors would affect the apparent mass of the anhydrous salt, and how that would affect the apparent mass of the water lost.) a. When massing the anhydrous salt, some water was observed to remain around the mouth of the test tube. b. The anhydrous residue decomposed upon heating, liberating a gas other than water vapor. c. The hydrate spattered during heating and some of the hydrate sample was lost.
