Mаteriаls: Three cleаn test tubes Test tube rack Five 5 mL Graduated pipet Hydrоgen perоxide Catalase (pоtato) Water pH 3 Water pH 7 Water pH 11 Ruler Wax pencil Procedure: Label each of your test tubes (P1, P2, and P3). To P1, add 1 mL of Catalase and 2 mL of water pH 3. To P2, add 1 mL of Catalase and 2 mL of water pH 7. To P3, add 1 mL of Catalase and 2 mL of water pH 11. Wait 1 minute before proceeding. Add 4 mL of hydrogen peroxide to all three test tubes. Carefully swirl the mix, wait 30 seconds, and record the bubble height (mm) in Table 4. Results: (Watch the Lab 7.
