When carbon dioxide dissolves in water, it undergoes a multistep equilibrium process, with Koverall = 4.5×10-7, which is simplified to the following: CO.(g) + H,O(1) H,CO;(aq) HCO, (aq) + H;O*(aq) H,CO3(aq) + H,O(1) (a) Classify each step as a Lewis or a Brønsted-Lowry reaction. (b) What is the pH of nonpolluted rainwater in equilibrium with clean air (Pco, in clean air = 4X10-4 atm; Henry's law constant for CO, at 25°C is 0.033 mol/L-atm)? (c) What is [CO,2-] in rainwater (K, of HCO,- = 4.7X10-11)? (d) If the partial pressure of CO, in clean air doubles in the next few decades, what will the pH of rainwater become?
