What do they form when they react with water?
metal hydroxide and hydrogen
Is the metal hydroxide solution acidic or alkaline?
alkaline
What is the solubility of group two hydroxides?
They become increasingly soluble as you go down the group
What is the solubility of group 2 carbonates?
They become decreasingly soluble as you go down the group
What is the trend of thermal stability of carbonates?
They become increasingly thermally stable as you go down the group
What does charge density depend on?
The charge and size of the ion
What is the trend of the charge density in group 2?
As you go down the group the charge density decreases
How are charge density and polarity linked?
Ions with a high charge density are good at polarising ions
