Acids and Bases
Measuring the pH of various solutions and classifying those substances as acids, bases, or neutral solutions.
PASPORT pH Sensor (PS-2102)
Lab Summary
In this experiment, students will measure the pH of various solutions and then use their data to classify those substances as acids, bases, or neutral solutions. The Danish chemist Soren Sorenson is credited with introducing the pH scale in 1909, giving scientists a means of characterizing a substance’s acidity on a scale of 0 to 14.
