Webb14 aug. 2013 · Ocean acidification occurs when CO2 is absorbed into the water at a high rate. It reacts with water molecules (H2O) to form carbonic acid (H2CO3). This compound then breaks down into a hydrogen ion (H+) and bicarbonate (HCO3-). The presence of all these hydrogen ions is what decreases the pH, or acidifies the ocean. Webb6 dec. 2024 · The experimental observation is that the pH of the top layer of the ocean has decreased by 0.1 unit, from 8.2 to 8.1 during the past century or so as about 100 GtC (≈ 370 Gt CO 2) have dissolved in the oceans. As more CO 2 dissolves, these concentration changes will continue and effects on marine life become evident.

WebbAt a pH of 7, this decreases to 0.0000001 M. At a pH of 14, there is only 0.00000000000001 M H+. pH stands for the “power of hydrogen” ³. The numerical value of pH is determined by the molar concentration of hydrogen ions (H+) ³. This is done by taking the negative logarithm of the H+ concentration (-log (H+)).
