The smaller is the size of cation, the more is heat of hydration. Since hydration is exothermic process, thus heat evolves and hence system having lower energy are stable.

Explanation:
Stability of Cuprous Compounds in Water:
Cuprous compounds such as CuCl, CuCN and CuSCN are the only salts stable in water due to the following reasons:
High Hydration Energy of Cu Ions:
The hydration energy of Cu+ ions is very high, which means that they have a strong affinity for water molecules. This high hydration energy helps to stabilize cuprous compounds in water.
Inherent Tendency Not to Disproportionate:
Cuprous compounds have an inherent tendency not to disproportionate, which means that they do not decompose into their constituent elements easily. This tendency also helps to stabilize them in water.
Diamagnetic Nature:
Cuprous compounds are diamagnetic in nature, which means that they do not have any unpaired electrons. This property also contributes to their stability in water.
Insolubility in Water:
Cuprous compounds are insoluble in water because of their low solubility product. However, they do not decompose in water due to their high stability.
Conclusion:
In conclusion, cuprous compounds such as CuCl, CuCN and CuSCN are the only salts stable in water due to their high hydration energy, inherent tendency not to disproportionate, diamagnetic nature and insolubility in water.
