प्रश्न
Compare the solubility and thermal stability of the following compounds of the alkali metals with those of the alkaline earth metals.
Sulphates
उत्तर
- Thermal stability-
Sulphates of both group 1 and group 2 metals are stable towards heat. - Solubility-
Sulphates of alkali metals are soluble in water. However, sulphates of alkaline earth metals show varied trends.
BeSO4 Fairly soluble
MgSO4 Soluble
CaSO4 Sparingly soluble
SrSO4 Insoluble
BaSO4 Insoluble
In other words, while moving down the alkaline earth metals, the solubility of their sulphates decreases.
