Group 2 reactions table

Group 2 reactions with oxygen & water chemical equations

Group 2 reactions with dilute hydrochloric acid & dilute sulfuric acid chemical equations

• The reaction of all metals with oxygen follows the following general equation:

2M(s) + O₂(g) → 2MO(s)

Where M is any metal in Group 2

Remember than 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)

Remember that SrSO₄ and BaSO₄ are insoluble
