The hydration energy of `Mg^(2+)` is larger than that of:

A

`Al^(3+)`

B

`Be^(2+)`

C

`Na^(o+)`

D

`K^(o+)`

Text Solution

Verified by Experts

The correct Answer is:
C, D
`Mg^(2+)`ion has greater charge/radius ratio as compared to `Na^(o+)` and `K^(o+)` and hence has higher hydration enthalpy.

Assertion: Aquated copper(I) cation undergoes disproportionation as: 2Cu^(+)(aq) to Cu^(2+)(aq)+Cu Reason: Hydration energy of Cu^(2+) is higher than that of Cu^(+) which compensates second ionisation energy of Cu.

Assertion: Aquated copper(I) cation undergoes disproportionation as: 2Cu^(+)(aq) to Cu^(2+)(aq)+Cu Reason: Hydration energy of Cu^(2+) is higher than that of Cu^(+) which compensates second ionisation energy of Cu.

Sodium sulphate is soluble in water whereas barium sulphate is sparingly soluble because (a) the hydration energy of Na_(2)SO_(4) is less than its lattice energy (b) the hydration energy of Na_(2)SO_(4) is more than its lattice energy (c) the lattice energy of BaSO_(4) is more than its hydration energy (d) the lattice energy has no role to play in solubility

The second ionisation energies are higher than the first ionisation energies. This is mainly due to the fact the after the removal of the first electron, the atom changes into monovalent positive ion. In the ion, the number of electrons decreases but the nuclear charge remains the same. as a result of this, the remaining electrons are held more tightly by the nucleus and it becomes difficult to remove the second electron. therefore, the value of second ionisation energy. (IE_(2)) , is greater than that of the first ionisatio energy (IE_(1)) . similarly third ionisation energy (IE_(3)) is greater than that of second IE_(2) . Q. IE_(1) and IE_(2) of Mg metal are 178 and 348 kcal/mol respectively. the energy required for the given reaction is: Mg(s) to Mg^(+2)+2e^(-)
