At room temperature, the solubility of which solute in water would be most affected by a change in pressure?
<h3><u>Explanation;</u></h3>
- As the pressure on a gas confined above a liquid increases, the solubility of the gas increases in the liquid.
- Carbon dioxide gas is most soluble in water under conditions of high pressure and low temperature.
- The solubility of gases decreases with increasing temperature, so the air space inside the cylinder when cold water is used will be less compared to warm water.
i think it will be A. im not sure
