Group 2

Question 1

Group 2 with OXYGEN and WATER (equations)

Answer 1

H2SO4, HCL and H2O, all form H2 + salt. Only with Oxygen they form MO, except Beryllium doesnt react with water, Mg reacts with water (steam) to form MgO, and BaO2 and SrO2 can form in reaction with oxygen

Question 2

Group 2 with dilute HCL and dilute H2SO4 (equations)

Answer 2

Question 3

How can you generally test for group 2 metal ions?

Answer 3

• Test Tube reaction
• Add Group 2 CHLORIDES to 4 separate tubes
• Add (Excess NaOH, Ammonia solution, Excess H2SO4) dropwise

Question 4

Positive results for presence of group 2 ions

Answer 4
