Under what circumstances will the solubility of gases in water increase?
A. Increasing P \& Increasing T
B. Decreasing Decreasing
C. Increasing Decreasing
D. Decreasing Increasing T
E. None of the above.
Studdy Solution
STEP 1
1. Solubility of gases in water is influenced by pressure and temperature.
2. Henry's Law applies, which states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid.
3. The solubility of gases typically decreases with an increase in temperature.
STEP 2
1. Analyze the effect of pressure on gas solubility.
2. Analyze the effect of temperature on gas solubility.
3. Determine the combination of pressure and temperature changes that increase gas solubility.
STEP 3
According to Henry's Law, increasing the pressure of a gas above a liquid increases the solubility of the gas in the liquid.
STEP 4
Typically, increasing the temperature decreases the solubility of gases in water because gases are more likely to escape from the liquid at higher temperatures.
STEP 5
To increase the solubility of gases in water, we need to increase the pressure and decrease the temperature.
