Preparation of [Cr(NH3)6](NO3)3 with Liquid Ammonia
Anhydrous liquid ammonia has a boiling point of -33.35 C, which might suggest that it would be a difficult material to handle, particularly in light of the familiar noxious odor of the gas. However, owing to hydrogen bonding, liquid ammonia has a relatively high heat of vaporization (23.3 J/mol vs. 40.7 J/mol for H2O). Thus, if kept in an insulated vessel (e.g., a Dewar flask), its rate of vapo...
