WebSeawater pH • pH = - log {H+} • The pH of seawater varies only between about 7.5 and 8.4 (i.e., slightly alkaline) • Over geological time, pH is thought to be controlled by water/mineral equilibria • Over shorter time scales (104 to 105 yrs) the CO 2 system (and its shifting equilibria) regulates seawater pH CO 2(aq) + H 2O ↔ HCO 3-+ H+ Web关注. 展开全部.
