As for the reaction itself, in the first step, H2O molecules come in and surround the Al3+, pointing the O ends toward it and the H ends away. This substance has been tested on rainbow trout, mice and rabbits to determine toxicity levels in animals. In order to study the effect of AlCl 3 on the hydrolysis of cellulose, we add 0.01% AlCl 3 to the solution and control the experiment at the same condition as previous study. In water, hydrogen chloride forms hydrochloric acid. The anhydrous material is important commercially. When dissolved in the human stomach, anywhere between 17 and 30 percent of the digested aluminum chloride is excreted through kidneys.
