Henry’s Law Constant (KH) represents the equilibrium between a gas and a liquid. It quantifies how much gas dissolves in a liquid at a given temperature and pressure. It is specific to each gas-solvent pair and is often expressed in units of mol/(L·atm). KH values vary with temperature, pressure, and the particular gas-solvent system.

How does KH affect the solubility of gas in liquid? KH (Henry’s law constant) directly affects the solubility of a gas in a liquid. A higher KH value indicates that the gas is more soluble in the liquid, while a lower KH value indicates lower solubility. Changes in KH with temperature or pressure can impact the gas’s solubility in the liquid.
How do you measure KH in water? KH (Henry’s law constant) is typically determined experimentally by measuring the concentration of a gas in a solution at various pressures and temperatures. The data is then used to calculate the KH value for the specific gas-solvent system.

What do K values tell you? Equilibrium constant (K) values in chemical reactions tell you about the position of the equilibrium. If K is significantly greater than 1, it indicates that the reaction favors the products at equilibrium.

If K is close to 1, it suggests that the reactants and products are present in similar amounts at equilibrium.
