2. (30 pts) The 2020 data collected by the National Trends Network (NTN) of the National Atmospheric Deposition Program (NADP) lists the following concentrations for Georgia rainwater: [NO₂] = 0.3 mg/L, [NH.] = 0.2 mg/L, [SO] = 0.3 mg/L, [Ca] = 0.05 mg/L, and [Mg²+] = 0.02 mg/L Relevant Equilibria: H₂0 H+ OH- H₂CO3H+ HCO pk = 14 pk = 6.35 pKaz= 10.33 HCO3+H+ + CO3²- CO,(aq) + CO2 Atomic mass data (g/mol): H = 1; C = 12; N = 14; O= 16; Ca = 40, Mg=24 Water density: 1000 g/L KH = 1420 atm a. Given that the atmosphere has 420 ppm, CO₂ at 25° and 1 atm, what is the concentration of carbonic acid [H₂CO3 *) in rain water? b. What is the pH of Georgia rainwater? Check any assumptions made. c. What is the carbonate alkalinity of Georgia rainwater in mg/L as CaCO3?
