oxalate ion造句

• It is an octahedral transition metal complex in which three bidentate oxalate ions are bound to an iron center.
• It is an octahedral transition metal complex in which three bidentate oxalate ions act as ligands bound to an iron centre.
• The oxalate method had to be performed quickly, as the oxalate ion was susceptible to radiolysis and the lanthanum had the tendency to go back into solution.
• The three oxalate ions donate 12 electrons in all and Fe-III has three electrons in the d orbitals leaving 13 empty places in the remaining d and p orbitals.
• The bonds to the iron atom are dative covalent bonds where the ligands, ( oxalate ions, blue ), donate a lone pair into the empty p and d orbitals of the transition metal ( iron, red ), atom.
• In this case, the reaction order " with respect to " the reactant HgCl 2 is 1 and with respect to oxalate ion is 2; the " overall " reaction order is 1 + 2 = 3.
• If this process is allowed to repeat over many months, such as leaving a container outside where it is exposed to the sun each day, eventually almost all of the oxalate ions present are oxidized to carbonate and the iron remains as Ferric Hydroxide, Fe ( OH ) 3.
• If a solution containing both green ferrioxalate ions and colourless free oxalate ions is exposed to strong light, such as direct sunlight, the light allows the Iron-III to oxidize one of the oxalate ligands to carbon dioxide and gives the orange-brown ferrooxalate complex ion which is coordinated around an Iron-II centre, however, when placed in the dark the Iron-II is re-oxidized to Iron-III by the oxygen in the atmosphere and the green ferrioxalate complex ion re-forms.
