The redox reaction within the PDMS has also been used to produce gold and silver nanoparticles from ionic species, but not nickel or iron nanoparticles from their metal ions. Would you expect PDMS to be used to produce zinc nanoparticles from zinc(II) ions? Why or why not?
Homework Answers
No because zinc can't undergoes redox reaction with PDMS to form zinc nanoparticles
?Its reactivity is higher as compared to silver and gold.It forms Zn (2+) ions.

Problem 1. Silver Nanoparticle Fate and Toxicity Several recent efforts to understand the potential risks of nanotechnology have focused on silver- containing nanoparticles, which are being used in consumer products to inactivate bacteria. In this problem, you will assess the aquatic toxicity of commercial silver nanoparticles. For simplicity, you can ignore ionic strength in this problem. You are given two water samples A and B. You put in each water sample 1 g/L of silver nanoparticles and allow the systems...

When species combine to produce a coordination complex, the equilibrium constant for the reaction is called is the formation constant, Kf. For example, the iron(II) ion, Fe2+, can combine with the cyanide ion, CN−, to form the complex [Fe(CN)6]4− according to the equation Fe2+(aq)+6CN−(aq)⇌[Fe(CN)6]4−(aq) where Kf=4.21×1045. This reaction is what makes cyanide so toxic to human beings and other animals. The cyanide ion binds to the iron that red blood cells use to carry oxygen around the body, thus interfering...
