1.	The low solubility of LiF and that of CsI in water are respectively due to which of the properties of the alkali metal ions ?
Answer» Higher hydration ENTHALPY of `Li^(+)` , higher lattice enthalpy of `CS^(+)` Smaller hydration enthalpy of `Li^(+)` , higher lattice enthalpy of `Cs^(+)` Smaller lattice enthalpy of `Li^(+)` , higher hydration enthalpy of `Cs^(+)` Smaller hydration enthalpy of `Li^(+)` , smaller lattice enthalpy of `Cs^(+)` SOLUTION :Due to SMALL SIZE , `Li^(+)` has a high lattice energy and due to the bigger size `Cs^(+)` has small hydration energy .
