Question

1 - Y is it so dat alkaline earth metals have more hydration enthalphy than alkali earth metals as size of alkaline earth metals is small than alkali metals??



2 - wht do v mean by saying that sulphate of alkaline earth metal r more stable to heat ?

Answer 1

A new resource for studying structure property relationships is presented, namely a systematic database of 36 organic salt structures together with phase specific aqueous solubility data. The salts are derived from four M2+ cations (Mg2+, Ca2+, Sr2+, Ba2+) and nine substituted benzoate anions. The intrinsic solubility of the free acid is found to have a major contribution to make to salt solubility, but despite previous literature assertions, there appears to be little correlation of solubility with the polarity of the organic ions, with cation …
