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 :)

1. what causes catalysts to be poisoned

  • only using them for frequent short periods
  • impurities in the reaction mixture
  • use over a long period of time
  • too high concentration fo water

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

  • platin reagent
  • Tollens reagent
  • Benedict's solution
  • Fehling's reagent

3. why are complexes with multidentate ligands more stable than those with unidentate ligands

  • ligand effect
  • stability effect
  • chelate effect
  • shielding effect

4. What are the side effects of using cisplatin as a cancer treatment

  • damage to red blood cells only
  • damage to hair cells,neutrophils and sometimes kidneys
  • damage to hair cells and red blood cells
  • damage to neutrophils and skin cells

5. why is a support medium used for heterogenous catalysts

  • to stop the catalyst getting lost within the products
  • the catalysts are very expensive and the surface area is increased
  • the support medium reacts with any impurities to remove them from the system
  • the catalyst needs to react with the support medium before it functions properly
