pH Scale
pH Scale
Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!

SOLVED: 1. Draw the pH scale from 0 to 14. 2. Indicate where on the scale it is acidic, basic, and neutral. 3. At pH 3 and pH 12, indicate the hydrogen ion concentration (For example, at pH 7, the hydrogen ion concentration is 0.0000001 M). 4. On the scale, show how the hydrogen ion concentration changes (increases or decreases) from neutral to acidic and from neutral to basic.
