'S i co-thàthadh ceimigeach gasach le foirmle NH3 a tha ann an amòinia.
Aig a bhrùthadh àbhaisteach tha amòinia a' goilidh aig −33.34 °C de theothachd. Tha amòinia glè sho-sgaoilte ann an uisge (47% cuideam aig 0 °C).
Eachdraidh
[deasaich | deasaich an tùs]Ann an 1774 rinn Joseph Priestley amòinia fìor-ghlan mar ghas agus chan e e "adhair alcaileach". Ann an 1785 dhearbhaich Claude Louis Berthollet gun robh trì pàirt haidridein airson gach pàirt naitridein ann an amòinia.[1]
Cleachdadh
[deasaich | deasaich an tùs]Ann an gnìomhachas dèanar amòinia aig am pròiseas Haber. Cleachdar e san saothrachadh stuth-mathachaidh agus chungaidhean-leighis.
