Question

How many of the following
energies are involved in the
transformation of
Nas) → Na+ (aq)?​

Answer 1

Three energies are involved in the transformation of  sodium to sodium ion

• During the transformation of sodium the following reactions takes place

            $Na(s)\rightarrow Na(g) (step1)$

            $Na(g) \rightarrow Na^{+}(g)+aq(step2)$

            $Na^{+}(g)+aq\rightarrow Na^{+}(g)(aq)(step3)$

• In step 1 of the reaction enthalpy of sublimation is used for the sodium to change from solid state to gaseous state

• Ionisation enthalpy is used to change sodium to sodium ion in the gaseous state

• In step 3 of the process the sodium ion in gaseous state changes into aqueos state using hydration energy
