On Tuesday, November 15th, 2016 HSA Dayton College Readiness Science classes investigated the pH level of household items by using different types of indicators. Household items were tested with different types of indicator and classified on the continuum of the pH scale range of 1 to 14. Firstly items were separated by using blue and red litmus paper as acid and base, then with pH strips, their pH scales were investigated. The results were reported in a table showing classification of the household items as acid and base, and pH results as well. The tested household items were; soda, orange juice, lemon juice, milk of magnesia, drain cleaner, mouthwash, glass cleaner, surface cleaner, bleach, water with electrolytes, ammonia, pickles, toilet bowl cleaner, degreaser.
