In this lesson, students will use the pH sensor to determine the pH level of various household solutions.  Alternative procedure for the Vernier Go Direct® sensors with TI-Nspire CX II is included in the downloads. 

• Use litmus paper and a pH Sensor to determine the pH values of household substances.
• Add cabbage juice to the same substances and determine different red cabbage juice indicator colors over the entire pH range.

In this experiment, you will use litmus and a pH Sensor to determine the pH values of household substances. After adding red cabbage juice to the same substances, you will determine the different red cabbage juice indicator colors over the entire pH range.
