Science Fair Projects - Testing Acids and Bases

Science fair projects testing acids and bases can be done using food products. Generally it will be easier to test liquids than solids because you will be using pH litmus papers. However, before you begin working on your food experiments, you need to understand the terminology and science concepts behind the experiments.

The first thing that you need to know when working with science fair projects testing acids and bases is how the pH scale is set up. The pH scale is color coded and numbered from 0 to 14. A pH litmus paper is saturated in a solution and then the color that develops is compared to the scale to determine how acidi, neutral or basic the solution is.

The second thing you need to know is what an acid is. An acid is a compound that has a pH level that is greater than 7. Acids include things like berries, beans, potatoes, milk and meats.

The third thing that you need to know when working with science fair projects testing acids and bases is what a base is. A base is a compound that has a pH level that is less than 7. Examples include watermelon, onions, spinach and olive oil.

Also, if the solution has a pH close to 7 then it is considered neutral. Neutral pH levels are best for the human bodies, and that is why it is important to learn how to acidic and basic foods together to help keep the body in balance. Heart burn is a common side effect of having too much acidic food. Antacids, as the name suggests, are designed to neutralize the acids in your stomach by adding alkaline.

Now that you know more about testing acids and basis you are ready to start working with your chemistry science fair projects. Before you try more advanced experiments it is a good idea to practice with basic experiments. For example, take some time to test a variety of solutions for their pH levels, including your own saliva.

After you have mastered testing pH levels you will be ready for more advanced projects. These projects will focus on applying what you learned about acids and bases to a problem. For example, your project may be to figure out how to create a dinner menu that will balance out as a neutral experience. This can be a very useful experiment, especially around the holidays when many people overindulge in acidic foods like meats.
