transition metals

Goes briefly through most sections of transition metals-hope it helps in your revision!

sorry about the weird notation of substances!- I have used ^ for any charges, some of the incorrect answers are made up words that sound similar :)

?
what is the definitoin of a transition metal
a metal that has at least 1 ion with an incomplete d-orbital
1 of 23
What is the colour of (Fe(H2O)6)^3+
yellow
2 of 23
(Fe(H2O)6)^2+ and dropwise ammonia is a ...reaction
deprotonation
3 of 23
what observation is seen with a 3+ complex and sodium carbonate
fizzing
4 of 23
(Cu(H2O)6)^2+ and excess ammonia forms...
(Cu(NH3)4(H2O)2)^2+
5 of 23
what is added to dichromate ions in order to form chromium(III) ions
Ruducing Agent
6 of 23
what is teh colour change when (Co(NH3)6)^2+ is oxidised to (Co(NH3)6)^3+
yellow to brown
7 of 23
what happens when excess ammonia is added to (Fe(H2O)3(OH)3)
no visible change
8 of 23
what colour is formed when excess ammonia is added to aqueous Co^2+ ions
straw colour
9 of 23
what shape does a complex with a coordination number of 6 usually form
octohedral
10 of 23
what shape is formed when large ligands eg Chloride ions bond to a transition metal ion
tetrahedral
11 of 23
cis platin takes what shape
square planar
12 of 23
why are complexes with multidentate ligands more stable than those with unidentate ligands
chelate effect
13 of 23
What are the side effects of using cisplatin as a cancer treatment
damage to hair cells,neutrophils and sometimes kidneys
14 of 23
what property of transition metals allow them to be good catalysts
variable oxidation states
15 of 23
what is the catalyst for the contact process
V2O5
16 of 23
what causes catalysts to be poisoned
impurities in the reaction mixture
17 of 23
why is a support medium used for heterogenous catalysts
the catalysts are very expensive and the surface area is increased
18 of 23
what factors influence the colour of complexes
coordination number, identity of ligand, identity of transition metal ion
19 of 23
what can EDTA^4- be used for
treatment for heavy metal poisoning

what reagent is (Ag(NH3)2) used in
Tollens reagent
