 Metal Notes Lithium (Li+) Can displace Hydrogen from liquid water, steam, and acids. Potassium (K+) Barium (Ba2+) Strontium (Sr2+) Calcium (Ca2+) Sodium (Na+) Magnesium (Mg2+) Can displace Hydrogen from steam and acids. Aluminum (Al3+) Zinc (Zn2+) Chromium (Cr2+, Cr3+) Iron (Fe2+, Fe3+) Cadmium (Cd2+) Can displace Hydrogen from acids. Cobalt (Co2+) Nickel (Ni2+) Tin (Sn2+) Lead (Pb2+) Hydrogen Antimony (Sb3+) Arsenic (As3+, As5+) Bismuth (Bi3+) Copper (Cu+, Cu2+) Mercury (Hg22+, Hg2+) Silver (Ag+) Palladium (Pd3+) Platinum (Pt2+, Pt3+) Gold (Au+, Au3+)

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
