Students will be able to explain that if two substances cause turn a pH indicator different colors, they must be different substances. Students will be able to explain that the color that a substance ...

A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves ...

Researchers have built a levitation device to help them make precise measurements of chemical reactions (Anal. Chem. 2020, DOI: 10.1021/acs.analchem.0c00929). Levitating droplets on sound waves allows ...

The tragic accident, when a restaurant manager in Massachusetts died, was the result of a simple chemical reaction called neutralization. That's when an acid and a base are combined. Unfortunately in ...
