When ammonia gas is dissolved in water, a basic solution of "ammonium hydroxide" (NH4+(aq) and OH (aq)) forms. Which of the following correctly describes the solubility of ammonia in water?

A decrease in solubility with increasing amount of solvent A decrease in solubility with increasing ammonia pressure An unusually large Henry's law constant A decrease in solubility with decreasing temperature

Explanation / Answer

Answer : An unusually large Henry's law constant

Explanaiton :

1) increasing amount of solvent increases the solubility

2) increases the ammonia pressure , increases the solubility

S = KH x P

3) decreasing temperature , increases the solubility of the gas.

so these three statements are wrong.

henry's law constant is large. so solublity increases.
