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 ...

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 ...

Due to the chemical nature of the sensing electrode, every pH probe experiences sensor drift over time. This drift is an ...

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 ...

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

Minnesota farmers are hovering near 99% compliance with a buffer law that’s been enforced since 2017. That’s a sign of success in a state filled with waterways, wetlands and over 14,000 lakes that are ...

A pH meter measures a pH or the acidity/alkalinity of substances. Most pH meters rely on a glass electrode that measures the number of hydrogen ions in the solution. Usually, pH meters need to be ...

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 ...
