    Before this first you have to know the relation between lattice energy and thermal stability ...In general, as thermal stability increases, the lattice energy also increases..

    Thermal stability depends upon the amount of heat required to break the ionic compound. Clearly, the stronger the bond between the ions is, the more heat will be required to break the bond and as a result, the thermal stability of the compound increases.

    Nitrates, carbonates and sulphates of alkali metals are water soluble. On moving down the group, the solubility increases. This is because their lattice energies decreases more rapidly than their hydration energies.

    So in moving down the group ,lattice energy decreases so thermal stability also decreases and thus solubility increases
