appropriate carbonic acid forms when co۲ dissolves in and reacts with water co۲ g h۲o h۲co۳ most dissolved co۲ occurs as aqueous co۲ rather than h۲co۳ but we write it as carbonic acid for convenience the equilibrium constant for the reaction is note we have a gas in the reaction and use partial pressure rather than activity first dissociation h۲co۳ hco۳– h first reaction second dissociation hco۳– co۳۲– h second reaction variables and reactions involved in understanding the carbonate system gas equilibria dissociation of carbonic acid dissociation of water cations measure ments pco۲ h۲co۳ h ca۲ dic hco۳– oh– alkalinity co۳۲– activity of carbonate species versus ph carbonate species and ph ph controls carbonate species increased co۲ aq increases h and decreases carbonate ion thus increasing atmospheric co۲ increases co۲ aq and causes the water system to become more acidic however natural waters have protecting buffering or alkalinity alkalinity refers to water s ability or inability to neutralize acids. the terms alkalinity and total alkalinity are often used to define the same thing. alkalinity is routinely measured in natural water samples. by measuring only two parameters such as alkalinity and ph the remaining parameters that define the carbonate chemistry of the solution pco۲ hco۳– co۳۲– h۲co۳ can be determined. total alkalinity sum of the bases in equivalents that are titratable with strong acid the ability of a solution to neutralize strong acids bases which can neutralize acids in natural waters hco۳– co۳۲– b oh ۴– h۳sio۴– hs– organic acids e.g. acetate ch۳coo– formate hcoo– carbonate alkalinity alkalinity ≈ hco۳– ۲ co۳۲– reason is that in most natural waters ionized silicic acid and organic acids are present in only small concentrations if ph around ۷ then alkalinity ≈ hco۳– closed carbonate system carbon dioxide is not lost or gained to the atmosphere total carbonate species ct is constant regardless of the ph of the system occurs when acid base reactions much faster than gas dissolution reactions equilibrium with atmosphere ignored total carbonate species ct how does co۳–۲ respond to changes in alk or dic ct h۲co۳ hco۳– co۳–۲ ~ hco۳– co۳–۲

photosynthesis is the biochemical process in which plants and algae harness the energy of sunlight to produce food. photosynthesis of aquatic plants and algae in the water occurs when sunlight acts on the chlorophyll in the plants. here is the general equation ۶ h۲ ۶ co۲ light energy — c۶h۱۲o۶ ۶ o۲ note that photosynthesis consumes dissolved co۲ and produces dissolved oxygen do . we can see that a decrease in dissolved co۲ results in a lower concentration of carbonic acid h۲co۳ according to co۲ h۲ h۲co۳ carbonic acid as the concentration of h۲co۳ decreases so does the concentration of h and thus the ph increases. cellular respiration cellular respiration is the process in which organisms including plants convert the chemical bonds of energy rich molecules such as glucose into energy usable for life processes. the equation for the oxidation of glucose is c۶h۱۲o۶ ۶ o۲ — ۶ h۲ ۶ co۲ energy as co۲ increases so does h and ph decreases. cellular respiration occurs in plants and algae during the day and night whereas photosynthesis occurs only during daylight. lithosphere linkage between the atmosphere and the crust igneous rocks acid volatiles sedimentary rocks salty oceans eq ۴.۱
