Researchers at the University of Illinois have found a simple solution to a problem that has plagued scientists for decades: the tendency of chemical buffers used to maintain the pH of laboratory ...

Question: What’s the difference between soil pH and buffer pH? My soil has a pH of 5.1 and a buffer pH of 6.7. Answer: Soil pH is the measure of active acidity. Active acidity is soil solution ...

This lab includes a theoretical explanation of how buffers work and how they are made, including a derivation of the Henderson-Hasselbalch equation. Students will use what they have learned to ...

This lab includes a demonstration of the proper use of a burette system for titrations; including a detailed description, instructional video, and opportunity for students to collect data to ...

Strong base is added to three different buffers and water and the effect on pH is observed.

Managing soil pH is crucial for maximizing crop yields and promoting overall soil health. The optimal soil pH is typically between 5.5 and 7.0 for most crops growing in Delaware. Maintaining a ...

A new analytical method that can measure a substance’s acidity in solution within minutes could take some of the hassle out of drug discovery. In lab studies on several common drugs, the tool—which ...
