Group 2 Flashcards
Mg with oxygen
burns easily, bright white light
Ca with oxygen
difficult to ignite, red flame
Sr with oxygen
difficult to ignite, red flame
Ba with oxygen
difficult to ignite, green flame
Mg with water
vigorous reaction with steam, no reaction with water
Ca with water
reacts moderately, forms a hydroxide
Sr with water
Reacts rapidly, forms a hydroxide
Ba with water
Reacts rapidly, forms a hydroxide
Mg with dilute HCL
reacts vigorously
Ca with dilute HCL
reacts vigorously
Sr with dilute HCL
reacts vigorously
Ba with dilute HCL
reacts vigorously
Mg with dilute H2SO4
reacts vigorously
Ca with dilute H2SO4
reaction slowed by the formation of a sparingly soluble sulfate layer on the metal, stopping hydrogen bubbles rising
Sr with dilute H2SO4
reaction is quickly stopped by the formation of an insoluble sulfate layer on the metal
Ba with dilute H2SO4
reaction is quickly stopped by the formation of an insoluble sulfate layer on the metal
magnesium with steam
Mg (s) + H2O (g) → MgO (s) + H2 (g)
metal with oxygen
2M (s) + O2 (g) → 2MO (s)
sr and Ba with oxygen
2Sr (s) + O2 (g) → 2SrO (s)
Sr (s) + O2 (g) → SrO2 (s)
metal with water
