Reactions of G2 with O2, H2O, dil HCl, H2SO4: Mg

O2 → burns easily, bright white light

H20 → vigorous reaction with steam → no reaction with water

dil HCl → reacts vigorously

H2SO4 → reacts vigorously

Reactions of G2 with O2, H2O, dil HCL, H2SO4: Ca

O2 → difficult to ignite - red flame

H2O → reacts moderately, form a hydroxide

dil HCl →reacts vigorously

H2SO4 → Reaction slowed by the formation of a sparingly soluble sulphate layer on the metal → stopping hydrogen bubbles from rising

Reactions of G2 with O2, H2O, dil HCL, H2SO4: Sr

O2 → difficult to ignite → red flame

H2O → reacts rapidly → forms a hydroxide

dil HCl → reacts vigorously

H2SO4 → reaction is quickly stopped by the formation of an insoluble sulphate layer on the metal

Reactions of G2 with O2, H2O, dil HCL, H2SO4: Ba

O2 → difficult to ignite → green flame

H2O → reacts rapidly → forms a hydroxide

dil HCl → reacts vigorously

H2SO4 → reaction is quickly stopped by the formation of an insoluble sulphate layer on the metal
