Human blood has a pH of approximately 7.4 due to the carbonic acid/bicarbonate ion (H2CO3/HCO3−) buffer system. Any pH changes below 6.8 or above 7.8 can lead to death! Carbonic acid dissociates to form water and carbon dioxide in the equilibrium shown below. This process is crucial in respiration. H2CO3 (aq) ⇋ CO2 (g) + H2O pKa1 = 2.77 Carbonic acid dissociates in water to form the bicarbonate ion and the hydroxonium ion by the following equilibrium reaction:H2CO3 (aq) + H2O ⇋ H3O(aq)+ + HCO3− pKa2 = 3.70 (i) If there is a 25% increase in carbonic acid levels as per pKa1, explain how the body would deal with this change.
A 2.2004 g of primary standard oxalic acid, H2C2O4 (90.04 g/mol), was dissolved in water to form a 250.00 mL solution. A 50.00 mL aliquot was taken for analysis and required 51.62 mL NaOH for titration. If the reaction is: H2C2O4 + 2NaOH ----> Na2C2O4 + 2H2O, what is the molarity of the NaOH solution?
