Which of the following changes will decrease the total amount of gaseous solute able to be dissolved in a liter of liquid water? (2 points) decreasing temperature decreasing pressure decreasing surface area decreasing solute concentration

Answer :

Answer: decreasing pressure

Explanation: Solubility of a gas is governed by Henry's law.

According to Henry's law, the solubility of a gas in a liquid is directly proportional to the pressure of the gas in equilibrium with the liquid at that temperature.

[tex]x_A=Kp_A[/tex]

where, [tex]x_A[/tex] = mole fraction of gas in the solution

[tex]p_A[/tex]= partial pressure of the gas above solution

K= constant

The solubility of gas increases with decrease in temperature.

Thus the solubility of gaseous solute will decrease when the pressure is decreased.
