Acid Rain is rain water that is unusually acidic due to elevated levels of carbonic acid within it. You sample the pH of 35 rain events in the Tri-cities area, finding the sample mean to be x ̄ = 5.20 and s = 0.71. Any rain events with a pH below 4 are considered acid rain. T

(a) State a null and alternate hypothesis to test whether or not you believe the typical rain event in the Tri-cities is an acid rain event.

(b) Select an appropriate α and evaluate your null hypothesis. Do you accept or reject it?

In the midst of the acid rain crisis in the 1980's, the average atmospheric SO2 levels were of the order of 150ppbv. Calculate the pH of natural rainwater at sea level in equilitrium with SO2(KH=5.4M-1atm, Ka1=1.7*10-2, Ka2=6.4*10-8) Assume that there are no other proton sources in the system. PPBV means ppb of volume.

Carbon dioxide dissolves in water to form carbonic acid, which is primarily dissolved CO2. Dissolved CO2 satisfies the equilibrium equation.The acid dissociation constants listed in most standard reference texts for carbonic acid actually apply to dissolved CO2. For a CO2 partial pressure of 3.2×10–4 bar in the atmosphere, what is the pH of water in equilibrium with the atmosphere? (For carbonic acid Ka1 = 4.46× 10–7 and Ka2 = 4.69× 10–11).
