"Challenges and solutions".
Title from resource description page (viewed August 14, 2018).
The majority of chemical reactions happen in solutions — whether inside an espresso machine or in a human cell. For example, when we breathe, the nitrogen in the air dissolves in our blood. Henry's Law gives us the power to predict, prevent, and treat "the bends" — a life-threatening condition that can happen to SCUBA divers when nitrogen in the blood comes out of solution and forms gas bubbles. Solution chemistry provides tools to measure the concentration of components of solutions, like the CO2 levels in ocean water. Knowing the concentrations of components in solutions can help determine the health of the world.
