Chemists have invented a new fluorescence-based method for accurately determining the strength of a range of Lewis acids, which could one day be used to help purify pharmaceutical drugs, improve ...

Frustrated Lewis pairs (FLPs) created a buzz in the chemistry community a decade ago when they were introduced as a metal-free catalytic system. A research team in Scotland has now taken the concept ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...
