Choose an option
Show full solutionCorrect option: A
Correct answer
AMg > Ca > Sr > Ba
Step-by-step explanation
Hydration power energy
Solubility order of IIA group element sulphates in water:
Generally bigger size ion form a strong bond with bigger ion so solubility will decrease or smaller the cation, greater the hydration sphere.
Hence, Solubility of ion with alkali or alkaline earth metal decrease top to bottom.
