The low solubility of LiF and that of CsI in water are respectively due to which of the properties of the alkali metal ions ?A. Higher hydration enthalpy of `Li^(+)` , higher lattice enthalpy of `Cs^(+)`B. Smaller hydration enthalpy of `Li^(+)` , higher lattice enthalpy of `Cs^(+)`C. Smaller lattice enthalpy of `Li^(+)` , higher hydration enthalpy of `Cs^(+)`D. Smaller hydration enthalpy of `Li^(+)` , smaller lattice enthalpy of `Cs^(+)` |
|
Answer» Correct Answer - D Due to small size , `Li^(+)` has a high lattice energy and due to the bigger size `Cs^(+)` has small hydration energy . |
