<p>I am confused about how to determine complex ions. Do you just have to memorize all the possible combinations of the cations with OH-, CN-, etc? Or is there a different way by looking at the molecular geometry?</p>
<p>My chem teacher told me that you basically have to memorize the complex ion stuff... like that OH- is hydroxo, NH3 is ammine, NH2 is amine, etc</p>
<p>complex ions are *****es.</p>
<p>I mean, is there any method to determine what complex iion form when given reactants, or do you just have to memorize them?</p>
<p>well usually complex ions are just metal and a ligand
just know some common ligands and if there is a reaction with a metal reactant you should know it’s a complex ion
for ex/
Fe3+ + SCN- = FeSCN2+
Fe is iron and SCN- is a common ligand</p>
