Question:
What are some examples of chemical equilibrium in the environment?



Replies:
There are literally thousands of chemical equilibria present in nature. A very short list is: the solubility of atmospheric gases in fresh and/or salt water, the solubility of carbonate minerals as a function of pH, photochemical reactions of "greenhouse gases" in the upper atmosphere, the concentration of oxygen as a function of depth and temperature in the ocean. These are but a few of many possible examples.
