Acids, Bases, and ph scale
Our project was on acids and bases. We took household items and tried to figure out whether it was an acid or a base. For our experiment, we took items like baking soda, orange juice, vinegar, and bleach and tested them out. Using litmus paper and an indicator we figured out where the item stood on the pH scale.
In order to determine if an acid, such as orange juice is acidic you must use blue litmus paper. If you are testing out a base, such as bleach, you must use red litmus paper. In our lab we found out which household items turned out to be acidic and which turned out to be a base. When it came to testing out powdery substance ,such as baking soda, we couldn't test it out it with litmus paper because it was not a liquid. Instead we poured cabbage juice which served as an indicator. The indicator then turned to a dark blue which makes it a base according to the pH scale. On the pH scale, the numbers less than 7 are acidic while the numbers more than 7 are bases. 7 is neutral meaning that is not an acid or a base. If a product on the pH scale is, for example, a 1 then the product is strongly acid. If it's a 14 then it is a strong base.
