Similarities and trends in the properties of the Group 2 metals, magnesium to barium, and their compounds
What this topic asks you to be able to do
- outline what happens when the elements react with oxygen and with water, and when they react with dilute hydrochloric and sulfuric acids, giving equations for these reactions
- outline the reactions of the oxides, hydroxides and carbonates with water and with dilute hydrochloric and sulfuric acids, giving the equations for these reactions
- describe the thermal decomposition of nitrates and of carbonates, giving equations, including the trend in thermal stability
- describe the trends shown by the elements that react in 10.1.1, and by the compounds in 10.1.2, 10.1.3 and 10.1.5, in their physical and chemical properties, and make predictions from these trends
- state how the solubility of the hydroxides and sulfates changes
