Nature of the graph between partial pressure of CO2 and its concentration in aerated drinks
Introduction
When CO2 is introduced into aerated drinks and sealed, it dissolves in the drink and establishes an equilibrium between the gas phase and the liquid phase. The concentration of CO2 in the drink depends on the partial pressure of CO2 in the gas phase, which in turn depends on the temperature and the amount of CO2 added.
Graph between partial pressure of CO2 and its concentration in aerated drinks
The graph between partial pressure of CO2 and its concentration in aerated drinks is a positive slope. This means that as the partial pressure of CO2 increases, the concentration of CO2 in the drink also increases. This relationship is governed by Henry's law, which states that the concentration of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid.
Explanation
The positive slope of the graph can be explained by the fact that when CO2 is added to the drink, it dissolves in the liquid until the partial pressure of CO2 in the gas phase is in equilibrium with the concentration of CO2 in the liquid. As the partial pressure of CO2 increases, more CO2 dissolves in the drink until the equilibrium is reached. Therefore, the concentration of CO2 in the drink increases with increasing partial pressure of CO2.
Conclusion
In conclusion, the nature of the graph between partial pressure of CO2 and its concentration in aerated drinks is a positive slope. This relationship is governed by Henry's law, which states that the concentration of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid.

CO2 obeys Henry’s law, which governs the solubility of gases in liquids in relation to its pressure. Henry’s law states that mole fraction of gas in the solution varies directly with its partial pressure over the surface i.e. p ∝ x (mole fraction). The graph is of the form y = mx, a positively sloped straight line passing through the origin.
