gizmo warm - up\nthe 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.\nthe ph analysis: quad color indicator gizmo 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.\n1. indicators change color in acids or bases. what is the color of the ph paper?
