How Acidic Waters Make Rocks Disappear, Salt Bridge Over Electrified Waters: How Electricity Changes pH. The pH scale is a measurement of how acidic or alkaline a substance is. The pH scale ranges from 1 to 14; 7 is neutral, lower numbers are acidic, and higher numbers are basic. Did they differ from what you expected? A neutral solution with a pH of 7, like distilled water, has the same number of hydrogen and hydroxyl ions. The pH of distilled water is between 5.6 and 7. For this reason, pH should not be confused with acidity and alkalinity.

The pH scale ranges from 1 to 14; 7 is neutral, lower numbers are acidic, and higher numbers are basic. Scientific Surprise A negative ion, formed when an atom gains electrons, is also called an anion. Acidic substances all have pH values below 7. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic). Your email address will not be published. How acidic is the rainfall in your area? Also, a standard coffee filter is recommended. Dissolved Oxygen vs. Acidic substances will show a yellow or red color, while basic substances will show blue. Experiment with how acid affects the environment or health. Add drops of vinegar, one drop at a time, to each jar.
