Experiment: Acids and Bases of Household Products Problem: Are these household products acids, bases or neutrals? Information Gathered: Acids have a high number of hydrogen ions but a low number of hydroxide ions. The pH of an acid range from 0 to 6.9 on the pH scale. Neutrals have an equal number of hydrogen and hydroxide ions. The pH of a neutral is 7. Bases have a high number of hydroxide ions, but a low number of hydrogen ions. The pH of a base range from 7.1 to 14 on the pH scale. The more hydrogen ions a substance have the stronger the acid will be. The more hydroxide ions a substance has the stronger the base will be. Hydrochloric acid is the strongest acid and sodium hydroxide is the strongest base. Hypothesis: It is believed that products 1-8 are acids, products 9-12 are neutrals and products 13-20 are bases. Materials List: Gloves, goggles, lab coat, paper towel, petri dish, chem plates, ruler, pencil, paper, colored pencils, lab sheets, pipets, pH strips, 20 products to sample, pH chart. Acids | Neutrals | Bases | 1. Hydrochloric acid 2. Mustard 3. Glycolic face mask 4. Maybelline fit makeup 5. Ear drops for swimmers ear 6. Nail polish remover 7. Aveeno baby eczema cream 8. Hair shampoo | 9. Clinique face protector 10. Banana boat kids sunscreen 11. Cosmetic primer 12. Blistex | 13. Active manuka honey 14. Eucalyptus oil 15. Rashberry vanilla mist 16. Jet dry 17. Hair spray 18. B+B hair undressing cream 19. Mr. Clean cleaner 20. Sodium hydroxide | Step by Step Procedure: 1. Put on lab coat, gloves 2. Put a small amount of household products into separate petri dishes 3. Removes gloves and throw them in trash can 4. Choose 20 household products to test by writing them in a list 5. Organize the chosen products into groups according to those believed to be acids, neutrals or
