As with the hydroxides, we find that whilst the carbonates of most
metals are insoluble, those of alkali metals are soluble, so that they
provide a good source of the carbonate ion COf ~ in solution; the
alkali metal carbonates, except that of lithium, are stable to heat.
Group II carbonates are generally insoluble in water and less
stable to heat, losing carbon dioxide reversibly at high temperatures.
