Gizmo Warm-up The strength of an acid or base is measured on the pH scale The term "pH is short for "potential of hydrogen." It is a measure of how many excess H ions there are in a solution. The pH scale runs from 0 to 14, with 0 representing the highest concentration of hydrogen ions. Acidic substances have a pH below 7, while alkaline substances (bases) have a pH above 7. Pure water has a pH of 7 and is considered neutral The pH Analysis Gumo allows you to find the pH of a variety of liquids. In the Gizmo, check that the Substance in the tube is Ammonia, and click Test Wait until the animation is finished 1. Indicators change color in acids or bases What is the color of the pH paper? Blue 2. Compare the paper to the pH color chart What is the pH of ammonia? 3 Is ammonia acidic or alkaline? LY
