Question

In the following pair of salts which one is more stable ? (a) Ferrous and Ferric salt (b) Cuprous and Cupric salt​

Answer 1

Among ferrous and ferric, ferric is more stable than ferrous and among cuprous and cupric salts, cupric is more stable

Answer 2

Answer:

The correct answer to the question-"In the following pair of salts which one is more stable ? (a) Ferrous and Ferric salt (b) Cuprous and Cupric salt​" is-

Explanation:

Stability in Salts-

In general terms, a chemical substance is known to be stable if it does not  react with the environment or during normal use, and  its useful properties are retained .

Stability of salts depends upon- whether the orbits are-“Half-filled and (a)  fully-filled orbitals are extra stable”.

(a) Ferrous and Ferric salt-

Ferrous salts are more unstable compared in comparision  to ferric  as ,half-filled 3d5 ,which have .3 d 5 configuration is more stable, therefore, ferric salts are more stable then ferrous salts.

   (b) Cuprous and Cupric salt​-

Since, energy is required to remove one electron from Cu+ to Cu2+, the high hydration energy of cupric salt here  compensates for it. Therefore, cupric ion in an aqueous solution is unstable

It give cupric ion  and Cuprious salt .The cupric ion has a greater charge density than cuprous ion and therefore ,forms much stronger bonds releasing more energy.

Stability depends on the hydration energy of the ions when they bond to the water molecules.

Therefore , among ferrous and ferric, ferric is more stable than ferrous and cuprous and cupric salts, cupric is more stable.
