One of the possible consequences of climate change is an increase in the temperature of ocean water. The oceans serve as a 'sink' for CO₂ by dissolving large amounts of it.
(a) The figure below shows the solubility of CO₂ in water as a function of temperature. Does CO₂ behave more or less similarly to other gases in this respect?

Key Concepts

Gas Solubility and Temperature

The solubility of gases in liquids generally decreases as temperature increases. This is due to the increased kinetic energy of gas molecules at higher temperatures, which makes them more likely to escape from the liquid phase into the gas phase. Understanding this principle is crucial for analyzing how CO2 behaves in ocean water as temperatures rise.

Henry's Law

Henry's Law states that the amount of gas that dissolves in a liquid at a given temperature is proportional to the partial pressure of that gas above the liquid. This law helps explain the relationship between CO2 levels in the atmosphere and its solubility in ocean water, particularly as temperature changes affect both pressure and solubility.

Impact of Climate Change on Ocean Chemistry

Climate change leads to rising ocean temperatures, which can alter the chemical balance of seawater. As temperatures increase, the ability of oceans to absorb CO2 diminishes, potentially leading to higher concentrations of CO2 in the atmosphere. This concept is essential for understanding the broader implications of climate change on marine ecosystems and global carbon cycles.
