Solubility: The solubility of the sulphates in water decreases down the groups i.e. Thus, while the solubility of BaSO 4 is only slightly greater in acidic solution than in water, the solubility … Carbonates of alkali metals are soluble in water with the exception of Li2CO 3. Solubility is the maximum amount a substance will dissolve in a given solvent. Be > Mg > Ca > Sr > Ba. However, carbonate of lithium, when heated, decomposes to form lithium oxide. The carbonates of alkaline earth metals can be regarded as salts of weak carbonic acid (H 2 CO 3) and metal hydroxide, M(OH) 2. The solubility of carbonates of alkaline earth metal decreases down the group mainly due to decreasing hydration enthalpies of the cations from Be 2+ to Ba 2+ . All the carbonates of alkaline earth metal are more soluble in the presence of CO 2 due to the formation of corresponding bicarbonates. But, the bicarbonates of alkaline earth metals are more soluble than their corresponding carbonates. We know that hydration energy and lattice energy are inversely proportional to the radii of the ions. Relevance. ... (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. Thus BeSO 4 and MgSO 4 are highly soluble, CaSO ­4 is sparingly soluble but the sulphates of Sr, Ba and Ra are virtually insoluble. Oxides. Although it describes the trends, there isn't any attempt to explain them on this page - for reasons discussed later. Any time you move down a group, the size (atomic radius) of the element increases. However, they dissolve in water containing CO 2 yielding bicarbonates, and this solubility decreases on going down in a group with the increase in stability of carbonates of metals, and decrease in hydration energy of the cations. The stability of carbonates and bicarbonates increases down the group. None of the carbonates is anything more than very sparingly soluble. The stability of the carbonates of the alkaline earth metals increases on moving down the group. Also, like the alkali metals, the alkaline earth metals form a wide variety of simple ionic salts with oxoanions, such as carbonate, sulfate, and nitrate. The carbonates of alkali metals are stable towards heat. Also, like the alkali metals, the alkaline earth metals form a wide variety of simple ionic salts with oxoanions, such as carbonate, sulfate, and nitrate. Answer. sluggermatt15. The nitrate salts tend to be soluble, but the carbonates and sulfates of the heavier alkaline earth metals are quite insoluble because of the higher lattice energy due to the doubly charged cation and anion.
