What is the trend in thermal stability of group 2 carbonates and nitrates as we move down the group?

The thermal stability of group 2 carbonates and nitrates increases as we move down the group,


This means they require higher temperatures to undergo thermal decomposition.

State and explain the trend in alkalinity of the solutions formed when group 2 oxides react with water.

The solutions become more alkaline as we move down group 2.


This is because the solubility of the group 2 hydroxides in water increases down the group, so the resulting solutions contain a higher concentration of OH-(aq) ions.
