Acid and Base Experiment
In this acid and base experiment, we will test the pH level of household items, such as vinegar, shower cleaner, spaghetti sauce, hydrogen peroxide, and more.
Cost: 10
Materials
- 1 package pH testing paper
- 8 to 12 bowls or containers
- Substances to test - orange juice, lemon juice, tea, coffee, sauces, household cleaners
- 1 pair lab glasses
- 1 pair disposable gloves
- 1 face mask, if testing aerosol cleaners
Instructions
- Determine what substances you are going to test. You might opt for food items.
- You might opt for cleaning solutions. We used these because we wanted to have a very alkaline test result. Please see the precautions listed below.
- Put on eye protection and gloves.
- Place a little of each substance into a small bowl or container. If using aerosol cleaners, go OUTSIDE, wear a mask, eye protection, and gloves before spraying a very small amount into the container. Hold the can very close to the container and away from other people.
- Label each container. You can make labels and place each container with its label.
- Dip one testing strip per container and place it on the surface next to the container. You may opt to put it on a paper towel or other dish to dry.
