Antacids: An Inquiry Study

Students use a pH sensor to investigate how antacid tablets work and use a back titration method to determine how much of the active ingredient is found in one tablet.

Supports NGSS Performance Expectation HS-PS1-7: Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.

Featured Equipment

pH Storage Solution

A 500 mL bottle of storage solution for PASCO pH Electrodes.

pH Buffer Capsule Kit

Use this kit to create fresh solutions of known pH values (4, 7 & 10) for calibrating pH meters or other purposes.

Electrode Support

Ideal for keeping sensors in place during experiments, this support connects to standard ring stands with an adjustable screw.

Wireless pH Sensor

Here’s the best tool for measuring pH since litmus paper. The Wireless pH Sensor connects via Bluetooth® to monitor the pH of solutions.

Support

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
