Single-Displacement Reaction
List of common metals that displace hydrogen from acids (arranged in order of reactivity)
Reactive Metals:
Lithium (Li) - Highly reactive
Potassium (K)
Barium (Ba)
Calcium (Ca)
Sodium (Na)
Magnesium (Mg)
Aluminum (Al)
Manganese (Mn)
Zinc (Zn) - Commonly used in lab
Chromium (Cr)
Iron (Fe)
Cadmium (Cd)
Cobalt (Co)
Nickel (Ni)
Tin (Sn)
Lead (Pb) - Slow reaction
Metals such as Copper, Mercury, Silver, Platinum, and Gold are below hydrogen in the activity series and cannot displace hydrogen from dilute acids.
