Unit 8 Chemical Equilibrium Focusing on Acid
... Equilibrium describes any condition or situation of balance. We recognize equilibrium in a chemical reaction system, oddly enough, by noticing nothing—we see no change in any property of the system. The easiest conclusion to draw would be that nothing is happening, but closer study reveals that, at ...
