Electrochemistry/Corrosion question

What is the redox equation for the formation of oxide layer on Ti-6Al-4V alloy? Pleasae include the cell potential value (if possible provide source/table).

Calculate E°cell for each of the following balanced redox reactions.

1.  

2.  

3.  

Are each of the reactions spontaneous?

Electrochemistry

Question 1 has 4 parts. Please explain each

a) Complete calculations of the standard reduction potentials for each half reaction listed below. Then, arrange the standard reduction potentials and corresponding half reactions in order, startting with the most positive at the top to the most negative at the bottom. All solutions are 1.0M, except for Ag1+ which is .1M. Use Nernst Equation to determine Eocell.

Values are Ag(-.44), Mg(1.70), Al(.87), Zn(1.6), Fe(.60), Sn(.55), Pb(.49), Cu(never changed)

b)Which of the values in part a have the strongest oxigation agents and the strongest reduction agents?

c)Why is it impo. that the precious metals Au, Ag, and Pt are poor reducting agents? What would happen if they weren't?

d)Write a balanced redox equation for the spontaneous reaction between the Cu/Ag half cells.
