# Problem: Glauber’s salt, Na 2SO4·10H2O, was used by J. R. Glauber in the 17 th century as a medicinal agent. At 25°C, Kp = 4.08×10−25 for the loss of waters of hydration from Glauber’s salt:             Na 2SO4·10H2O(s) ⥫⥬ Na2SO4(s) + 10H2O(g)(b) How do the following changes affect the ratio (higher, lower, same) of hydrated form to anhydrous form for the system above?(1) Add more Na 2SO4(s)(2) Reduce the container volume(3) Add more water vapor(4) Add N2 gas

Remember the Le Chatelier’s principle: If a system (chemical reaction) is at equilibrium and we disturb it then the system will readjust to maintain it’s equilibrium state.

Glauber’s salt, Na 2SO4·10H2O, was used by J. R. Glauber in the 17 th century as a medicinal agent. At 25°C, Kp = 4.08×10−25 for the loss of waters of hydration from Glauber’s salt:
Na 2SO4·10H2O(s) ⥫⥬ Na2SO4(s) + 10H2O(g)

(b) How do the following changes affect the ratio (higher, lower, same) of hydrated form to anhydrous form for the system above?
(2) Reduce the container volume
