Analytical Chemistry of Group 2 Metals

Atomic absorption is also useful for the alkali metals, data are given with the data for group 2 metals in the next section. Although flame photometry is also suitable for the alkali metal, the difficulty of obtaining reproducible results makes the technique less reliable for quantitative work. 

Because these metals form more insoluble compounds and more stable complexes, titrimetric, gravimetric and instrumental methods are available for their determination.
