From the given activity series, Al is higher in the activity series than hydrogen and Al can displace hydrogen acids.
Only A. 2.15 g Al can be dissolved by HI.
Oxidation reaction: Al → Al3+ + 3e-
HI → H+ + I-
Reduction Reaction: 2 H+ + 2 e- → H2
Determine whether HI can dissolve each metal sample. If it can, write a balanced chemical reaction showing how the metal dissolves in HI and determine the minimum volume of 3.5 M HI required to completely dissolve the sample.
A. 2.15 g Al
B. 4.85 g Cu
C. 2.42 g Ag
