Question 1

What is a Henry's Law?

Accepted Answer

Henry's Law states that at constant temperature, the concentration of a dissolved gas in a liquid is directly proportional to the partial pressure of that gas above the liquid. C = P / kH.

Question 2

How does the Henry's Law work?

Accepted Answer

C = P / kH (where kH is Henry's law constant, units L·atm/mol) Then: Or: P = kH × C Then: Temperature-dependent: gases become less soluble at higher temperatures Then: kH for O₂ ≈ 769 L·atm/mol · kH for CO₂ ≈ 29.4 L·atm/mol.

Question 3

Can you give an example of how to use the Henry's Law?

Accepted Answer

Example: Input CO₂ at 1 atm · kH=29.4 L·atm/mol gives a result of C = 1/29.4 = 0.034 mol/L (Dissolved CO₂ in carbonated drinks).
