Question
CuSO4.5H2O(s) $\rightleftharpoons$CuSO4.3H2O(s) + 2H2O(g), KP for this equilibrium is 1.0 × 10−4 atm2 at 25oC. What is the maximum pressure of water vapour (moisture) in the atmosphere, below which the pentahydrate is efflorescent?
Options
A.7.60 mm
B.0.01 mm
C.0.076 mm
D.760 mm
Solution
For pent hydrate to be efflorescent, Q < Kp
Or, $P_{H_{2}O}^{2} < 10^{- 4}\text{ at}\text{m}^{2}$
$\Rightarrow P_{H_{2}O} < 10^{- 2}\text{ atm = 7.6 mm}$
