- All Group 2 oxides and hydroxides are bases.
- They will neutralise by adding an acid to form a salt.
- When you add water to an oxide it forms an hydroxide... Ca (OH)2
- When you add an hydroxide to water it forms an alkaline solution, AS YOU GO DOWN THE GROUP THE SOULTION BECOMES MORE ALKALINE
- Because there are more OH- ions present
- They are decomposed to form a metal oxide + carbon dioxide
- AS YOU GO DOWN THE GROUP…
