Weak Acid Titration

In this lab, students will use a drop counter and pH sensor to titrate monoprotic and polyprotic weak acids. Then they'll determine the relationship between the shapes of the curves and Ka.

Featured Equipment

Wireless Drop Counter

Wireless Drop Counter

Use the new Wireless Drop Counter for more efficient and accurate titration data. Conducting a titration has never been easier!

pH Sensor

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.

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.
