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

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 ...

Identify the independent (manipulated) and dependent (responding) variables in a scientific investigation. Draw conclusions about the relationship between two variables using quantitative data.

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 ...
