Forgetting that caused AR4 to predict a decline from about 8.2 to 7.8 by 2100 thanks to their forecast of rising CO2. The correct calculation given buffering is to 8.05. Second, ocean pH is highly dependent on biological activity in the photic zone. 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+)).
