We’re being asked to determine whether HI can dissolve the given metal sample, write a balanced reaction, and the volume of 3.5 M HI required to completely dissolve the sample.
Recall the reaction for a S.H.E.: 2 H+(aq) + 2 e- → H2(g)
Properties of a Standard Hydrogen Electrode (S. H. E.)
Which of the following is NOT true of a standard hydrogen electrode

III. It contains H2 gas at a pressure of 1 atm.
A. only I
B. only III
C. I and III
D. only II
E. all the statements are true
F. I, II, and III
