Error Analysis Questions for Alum Synthesis Experiment 1. After collecting the alum product from the synthetic experiment, a chemist calculates a percent yield of 108.9%. What does this suggest regarding the purity of the resulting two possible reasons for such a high percent yield. 2. Assuming the sulfuric acid (H SO.) added is insufficient to fully react with all of the Al(OH),, how would this affect the theoretical yield of alum.
