The rule here is ions of similar size attract one another strongly, and thus do NOT dissociate or become soluble in solution. Decomposition reaction. Alkali metals hydroxides being strongly basic react with all acids forming salts. Even ignoring entropy (to a first approximation we might assume that the entropy change is constant for all the metals), solubility depends on both lattice energy and hydration enthalpy so you can't just look at one trend. In chemical terms, all of the alkaline metals react with the halogens to form ionic alkaline earth metal halides. Here we shall look at the solubilities of the hydroxides and sulfates of Group 2 metals. As a result, larger cations form STRONGER bonds with larger anions (CO3 is considered a decent size anion).
