Enthalpy of Hydration:
Enthalpy of hydration refers to the amount of energy released or absorbed when the ions are hydrated. It is an exothermic process, i.e., energy is released when the ions are hydrated.
Order of Enthalpy of Hydration for Transition Metal Ions:
The order of enthalpy of hydration for transition metal ions is determined by the effective nuclear charge, size of the ion, and the degree of hydration.
The correct order of enthalpy of hydration for the transition metal ions is Ni2+ > Co2+ > Cr2+ > Mn2+.
Explanation:
The correct order of enthalpy of hydration for the transition metal ions is Ni2+ > Co2+ > Cr2+ > Mn2+. This can be explained as follows:
- Effective Nuclear Charge: The effective nuclear charge of the ion increases from left to right in the periodic table. Therefore, the enthalpy of hydration increases from left to right.
- Size of the Ion: The size of the ion decreases from left to right in the periodic table. Therefore, the enthalpy of hydration increases from left to right.
- Degree of Hydration: The degree of hydration increases with the increase in the charge of the ion. Therefore, the enthalpy of hydration increases with the increase in the charge of the ion.
So based on the above three factors, the correct order of enthalpy of hydration for the transition metal ions is Ni2+ > Co2+ > Cr2+ > Mn2+.
Conclusion:
The correct order of enthalpy of hydration for the transition metal ions is Ni2+ > Co2+ > Cr2+ > Mn2+. This order is determined by the effective nuclear charge, size of the ion, and the degree of hydration.
