Question

Let's assume, CO gas is dissolved in water till the saturation level. If we will increase the temperature of the water then what will happen?

• A. More CO gas will start dissolving
• B. CO gas will be released
• C. There will be no effect of temperature on solubility
• D. None of these

Answer 1

The correct option is B

CO gas will be released

Solubility of gases in liquids decreases on increasing temperature. So CO gas will be released on increasing temperature. A similar observation is seen when boiling water, the dissolved oxygen in water starts escaping in the form of bubbles as the temperature of the water is increased.
