Question

why solubility of Glauber’s salt decreases after a certain temperature?​

Answer 1

Answer:

Upto 32.4∘C, Glauber's salt remains in the hydrated form whose dissolution is endothermic. ... Beyond 32.4∘C, it changes into anhydrous salt whose dissolution is exothermic. Hence, solubility decreases with increase of temperature.
