Doubtnut is better on App. (iii) Solubility of hydroxides of alkali metals are higher than that of alkaline earth metals. Together with hydrogen they constitute group 1, which lies in the s-block of the periodic table.All alkali metals have their outermost electron in an s-orbital: this shared electron configuration results in their having very similar characteristic properties. Solubilities of the halides, nitrates, carbonates, sulfates, and some perchlorates of all the alkali metals and alkaline earth metals in methanol at room temperature have been determined. Due to lower ionization enthalpy, alkali metals are more electropositive. Solubility in water is related to the ionic nature and size. Now you know, what you should do.
