Q
The solubility of Group 2 sulfates decreases down the Group.
Explain this trend.
Ref: 9701/41/O/N/16
A
hydration enthalpy and lattice energy both more endothermic / more positive / less exothermic / less negative (down the group)
∆Hhyd decreases more / faster and ∆Hsol becomes (more) endothermic /(more) positive / less exothermic / less negative
