Definition
Antimonious describes compounds containing antimony in its lower oxidation state, commonly with a valence of +3. Think of it as the "other" form of antimony, distinct from 'antimonic'. These antimonious compounds often have different properties and applications than their antimonic counterparts. They can be found in various chemical reactions and industrial processes. Antimonious compounds are often used in pigments and mordants. It's all about how antimony is bonding!
