Question 1

Consider an electrochemical cell with a zinc electrode immersed in 1.0 M Zn2+ and a silver electrode immersed in 1.0 M Ag+.

    Zn2+ + 2e–→ Zn        E° = –0.758 V

    Ag+ + e–→ Ag          E° = 0.800 V

Calculate E° for this cell.


◦ 0.042 V
◦ –0.042 V
◦ 1.558 V
◦ –1.558 V
◦ None of these are correct.

Question 2

Consider an electrochemical cell with a zinc electrode immersed in 1.0 M Zn2+ and a nickel electrode immersed in 0.10 M Ni2+.
Zn2+ + 2e-→ Zn
E° = –0.76 V
Ni2+ + 2e-→ Ni
E° = –0.23 V
  

 Calculate the concentration of Ni2+if the cell is allowed to run to equilibrium at 25°C.

​

Reference: Ref 18-4

​

​


◦ 1.10 M
◦ 0.20 M
◦ 0.10 M
◦ 0 M
◦ None of these are correct.

Did you know?

Lower drug doses for elderly patients should be used first, with titrations of the dose as tolerated to prevent unwanted drug-related pharmacodynamic effects.

Did you know?

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).

Did you know?

Multiple sclerosis is a condition wherein the body's nervous system is weakened by an autoimmune reaction that attacks the myelin sheaths of neurons.

Did you know?

Alzheimer's disease affects only about 10% of people older than 65 years of age. Most forms of decreased mental function and dementia are caused by disuse (letting the mind get lazy).

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
