Question 1

Using the following standard reduction potentials,

Fe3+(aq) + e- →Fe2+(aq)E° = +0.77 V
Ni2+(aq) + 2 e- →Ni(s)E° = -0.23 V

calculate the standard cell potential for the galvanic cell reaction given below and determine whether or not this reaction is spontaneous under standard conditions.

Ni2+(aq) + 2Fe2+(aq) → 2Fe3+(aq) + Ni(s)

◦ E° = -1.00 V, spontaneous
◦ E° = -1.00 V, nonspontaneous
◦ E° = +1.00 V, spontaneous
◦ E° = +1.00 V, nonspontaneous

Question 2

Given that E°red = -1.66 V for Al3+/Al at 25 °C, find E° and E for the concentration cell expressed using shorthand notation below:

Al(s) ∣ Al3+(1.0 × 10-5 mol L-1) ∣∣ Al3+(0.100 mol L-1) ∣ Al(s)

◦ E° = -1.66 V and E = -1.54 V
◦ E° = 0.00 V and E = +0.0789 V
◦ E° = -1.66 V and E = -1.42 V
◦ E° = 0.00 V and E = +0.24 V

A cataract is a clouding of the eyes' natural lens. As we age, some clouding of the lens may occur. The first sign of a cataract is usually blurry vision. Although glasses and other visual aids may at first help a person with cataracts, surgery may become inevitable. Cataract surgery is very successful in restoring vision, and it is the most frequently performed surgery in the United States.
