Is the dissolution of a gas in a solvent exothermic?

May 6, 2017

Answer:

Now generally, to degas a solvent, typically water, WE BOIL it......

Explanation:

And we can represent this by the equation:

$\text{Dissolved gas in water" +Deltararr"Degassed water"+"Gas in air}$

Because we have had to supply energy to break up the solute/solvent interactions, the reaction as written is ENDOTHERMIC. It follows that the initial dissolution of the gas in the solvent was EXOTHERMIC. Does you agree?
