Product Details

Produce something new—synthesize! Aluminum potassium sulfate (alum) is used for many different purposes—from pickling foods to aftershave for men. Students perform a multi-step chemical reaction starting with a common household ingredient—aluminum foil. Add potassium hydroxide, sulfuric acid, water and the techniques of dissolution, crystallization, and filtering to produce solid alum. Students also calculate percent yield and perform a post-lab cost analysis. Includes reproducible handouts, detailed background information, complete Teacher Notes with sample data and answers to questions, and all necessary chemicals. Complete for 30 students working in pairs. Apparatus for gravity filtration and a full aspirator filtration assembly is required and available separately. Perform this experiment in a fume hood or well-ventilated lab.
