A hypothetical lake has a surface area of 23 acres and an avgage depth of 20 ft. Recently there was an accident where a truck spilled 9,000 gals of concentrated H2SO4 (18M) directly into the lake. Assume there are no inputs or outputs to the lake and all the water in the lake is well mixed.
if the lake was pure water, with an initial pH of 7.2 what would the final pH be after the spill?
H2SO4 - pKa1 = strong, pKa2 = 1.92
