    Arrhenius Example
Click For Summary
Ammonia (NH3) serves as a prime example of a Bronsted-Lowry base, as it accepts protons but does not qualify as an Arrhenius base because it does not dissociate hydroxide ions in water. Instead, ammonia can engage in autoionization, demonstrating its amphoteric nature. The discussion emphasizes that while ammonia can act as a Lewis base by donating a pair of electrons, the focus remains on its classification as a Bronsted-Lowry base without delving into Lewis acid-base theory.

Could someone give and example of a substance that is a Bronsted-Lowry base, but not an Arrhenius base..
 
Chemistry news on Phys.org
Ammonia (NH3)

Accepts a proton (Bronsted-Lowry), yet does not disassociate hydroxide ions into water (not Arrhenius)
 
no think about Lewis acids/bases

Lewis bases are defined as being able to donate a pair of electrons, ammonia also falls into this category... is that what you mean?

NH3 is generally regarded as not an Arrhenius base since it autoionizes and is amphoteric:

NH3 + NH3 ⇄ NH4+ + NH2-

Thread 'Gold hydride - what is the significance?'

I came.across a headline and read some of the article, so I was curious. Scientists discover that gold is a 'reactive metal' by accidentally creating a new material in the lab https://www.earth.com/news/discovery-that-gold-is-reactive-metal-by-creating-gold-hydride-in-lab-experiment/ From SLAC - A SLAC team unexpectedly formed gold hydride in an experiment that could pave the way for studying materials under extreme conditions like those found inside certain planets and stars undergoing...
