Let's assume that there is 400 μatm of pCO2 in our atmosphere. Assuming there is nothing else in the water coming from the atmosphere, what is the pH of rainwater in equilibrium with this atmospheric CO2? Assume KH = 5.4x10-2 mol kg-1 atm-1. KC1 = 3.47×10-7 mol2 kg-2 for freshwater rain. Hint: Because rainwater is acidic, it has little/no alkalinity, thus the (H+] = Alk = [HCO3-]
