ammines造句

• They are extracted from their ores as ammine complexes with aqueous ammonia.
• The ammine ligands are more acidic than is ammonia ( pK a ~ 33 ).
• Unlike the hydroxides of aluminum and lead, zinc hydroxide also dissolves in excess aqueous ammonia to form a colorless, water-soluble ammine complex.
• The term " ammine " refers to hexa-" ( Greek : six ) indicates that there are six ammonia molecules per cation.
• This coordination complex, a typical Werner-type complex, consists of a central cobalt atom coordinated by six ammine orthogonal ligands and three chloride counteranions.
• Ammine complexes of chromium ( III ) were known in the late 19th century, and formed the basis of Alfred Werner's revolutionary theory on the structure of coordination compounds.
• Here ( NH 3 ) 6 indicates that the ion contains six [ ammine | NH 3 groups ], and [ ] encloses the entire formula of the ion with charge + 3.
• The deprotonation of cobalt ( III ) ammine-halide complexes, e . g . [ CoCl ( NH 3 ) 5 ] 2 + labilises the Co-Cl bond, according to the Sn1CB mechanism.
• Besides, when the concentration of ammonia solutions is very high, divalent copper ions in presence of dioxygen, catalyze ammonia oxidation, giving rise to copper ammine nitrites : Cu ( NO 2 ) 2 ( NH 3 ) n;
• I can't answer all your question but I can tell you than ammonia solution ( also known as ammonium hydroxide or aqueous ammonia ) will help to dissolve Fe0, MnO . It's ability to dissolve these compounds depends on forming ammine complexes of the metal ion.
• Neutral compounds such as " cis "-platin and ammine and nitro complexes such as [ Pt ( NH 3 ) 4 ] Cl 2, K 2 [ Pt ( NO 2 ) 4 ] and platinum nitrate are not considered to be allergenic; neither is the metal.
