Reactions of Group 2 Elements
- Although there is no required practical specifically based around the reactions of Group 2 elements, these reactions are important and students tend to not do very well on these questions in the exam
- Practical style questions can be asked on this topic - you should learn this in detail
Reactions of Group 2 Elements
- The reaction of all Group 2 metals with oxygen follows the following general equation:
2M (s) + O2 (g) → 2MO (s)
Where M is any metal in Group 2
- Sr and Ba also form MO2
- The reaction of all metals with water follows the following general equation:
M (s) + 2H2O (l) → M(OH)2 (s) + H2 (g)
Except for, Be which does not react with water
- The reaction of all metals with dilute HCl follows the following general equation:
M (s) + 2HCl (aq) → MCl2 (aq) + H2 (g)
- The reaction of all metals with dilute H2SO4 follows the following general equation:
M (s) + H2SO4 (aq) → MSO4 (aq) + H2 (g)
- SrSO4 and BaSO4 are insoluble
