Factors Affecting Solubility of Gases in Liquids

Q.

What is the effect of pressure on solubility of gases? Explain with an example.

Q.

how does the solubility increase when we increase the temperature of a solution?

Q.

How does the increase in temperature affect the solubility of solids and gases?

1. With rise in temperature, the solubility of a solid increases

2. With fall in temperature, the solubility of a gas decreases

3. With rise in temperature, the solubility of a gas increases and with fall in temperature the solubility of a solid increases

4. With rise in temperature, the solubility of a gas increases

Q.

What is the difference between deliquescency and hygroscopy

Q.

Explain three factors that affect the solubility of solvent and solute. [3 MARKS]

Q.

A boy was carrying out an experiment on the solubility of a gas in the water.He took a solute gas A and dissolved it in a liquid solvent(Water) B at a particular temperature T and pressure P.At that point he got some solubility value S. Later, he observed the value of solubility by

i)increasing temperature of water from T to T' and

ii)decreasing pressure on water surface from P to P'.

He got the new solubility S'.Then what is the relationship between former solubility S and latter solubility S'?

1. S' < S

2. S' = S

3. S' = 2S

4. S' > S

Q.

The Fig. shows a simple arrangement of the fountain experiment.

What is the property demonstrated by this experiment?

1. High saturation of the gas in water
2. Low saturation of the gas in water
3. High solubility of the gas in water
4. Low solubility of the gas in water

Q. CO gas is dissolved in water till the saturation level. What will happen if the temperature of water is increased?

1. More CO gas will start dissolving
2. CO gas will be released
3. Solubility is not affected by temperature
4. Water will turn into ice

Q.

Write the name of one substance whose solubility increases rapidly with the rise of temperature.

1. decreases

2. remains same

3. cannot be determined

4. increases

Q.

What is the effect of pressure on solubility of gases? Explain with an example.
