FAQ

Frequently Asked Questions

No, it is a highly specialised term used only in advanced chemistry.

Typically, it refers specifically to cobalt(III) complexes with ammonia ligands, not simple mixtures or cobalt(II) species.

They were crucial in Alfred Werner's work in the 1890s, which established the modern theory of coordination chemistry and won him the Nobel Prize.

It is pronounced with primary stress on the second syllable 'balt', and secondary stress on the last syllable 'mine': /koʊˈbɑːltəˌmiːn/ (US) or /kəʊˈbɔːltəˌmiːn/ (UK).

A specific inorganic coordination compound in which cobalt ions are bonded to ammonia molecules (NH₃).

Cobaltammine is usually technical / scientific in register.

Learning

Memory Aids

Mnemonic

Think: COBALT + AMMONIA = cobaltammine. It's where cobalt meets amine groups from ammonia.

Conceptual Metaphor

N/A. The term is a literal, technical descriptor.
