17B.1 Flashcards
What are the four main types of reactions when it comes to transitional metals
- redox
- deprotonation
- ligand exchange
- coordinate number chnage
what is redox reactions with transition metal
the oxidation number of transition metal ion changes
what are deprotonation reactions with transition metal
the removal of one or more hydrogen ions (protons) from a complex ion
what are ligand exchange reactions with transition metal
when one ligand in a complex ion is replaced by a different ligand
what are coordinate number change reactions with transition metal
the number of ligands changes
what is the colour of iron(ii)
pale green
what is the colour of iron(iii)
brown
what are the best ways to illustrate colour changes in ligand reaction due to oxidation and etc
by having the complex be in solid form, or crystals
when iron(ii) is left in the air what will happen
its pale green colour will gradually change to brown as iron(ii) will be oxidised and will form iron(iii)
what are the reaction, reaction type, and colour change when Hexaaquacupper(ii) and sodium hydroxide react
page 199
what is the difference between a ligand exchange reaction and deprotonation
deprotonation is just when another ligand takes hydrogen from a ligand within the complex and doesn’t replace it, but the ligand exchange reaction is when another ligand completer replaces the ligand in the complex ion, sometimes it might look like the reaction is ligand exchange so we need to be careful and look at the products formed
how can tetramminecupper(ii) sulfate - 1 - water be formed using ligand exchange
page 199
in deprotonation, the number of ligands used to take the hydrogen is equal to
usually the charge of the complex
what are the reaction, reaction type, and colour change when tetraaquadihydroxocupper(ii) complex (which usually comes from Hexaaquacupper(ii) and sodium hydroxide reaction) reacts with ammonia

what are the reaction, reaction type, and colour change for the formation of tetrachlorocurrtae(ii) complex from hexaaquacupper(ii)
