When books containing ''sized'' paper are stored in a high-humidity environment, Al2(SO4)3 absorbs moisture, which eventually leads to the production of H+ ions. The H+ ions catalyze the hydrolysis of cellulose by attaching to the shaded 0 atoms in cellulose. The long chain unit of glucose units breaks apart, resulting in the crumbling of the paper. Write equations for the production of H+ ions from Al2(SO4)3.
