Question

How does the pressure of a gas over a liquid affect the quantity of gas that dissolves in solution?A.As pressure increases, the quantity of gas that dissolves decreases.B.As pressure increases, the quantity of gas that dissolves increases.C.As pressure increases, the quantity of gas that dissolves decreases to a point and then levels off.D.Pressure has no effect on the quantity of gas that dissolves in a liquid.

Answer 1

• As you increase the pressure of a gas, the collision frequency increases and thus the solubility goes up.

,

• This means that as pressure increses, the quantity of the gas that dissolves( solubility) also increases.

,

• Option B is correct. [increase in pressure = increase in gas solubility.]
