Chapter 2: Q22 P (page 44)

Which drying agent is more efficient, Drierite or phosphorus pentoxide?

Short Answer

Expert verified

Phosphorus pentoxide is more efficient.

Step by step solution

01

Definition of Drierite

Drierite (calcium sulphate, $C a S O_{4}$ ) and phosphorus pentoxide $(P_{4} O_{10})$ are two drying agents with different efficiencies.

02

Determine which drying agent is more efficient among Drierite and phosphorus pentoxide

Drierite: $67 μ g H_{2} O / L$

Phosphorus pentoxide: $3.6 μ g H_{2} O / L$

As a result, we may deduce that phosphorus pentoxide is a more efficient drying agent since it absorbs more water per litre from the atmosphere
