Question

1. Alkalinity. (+6 total) Prior to the industrial revolution, the concentration of bicarbonate and carbonate in the ocean was 110 mg/L and 14.7 mg/L, respectively, and the pH was 8.2.

a. Calculate the total alkalinity (in mg/L as CaCO3) of the ocean prior to the industrial revolution. b. Today, the pH of the ocean is 8.1. Assuming that the concentration of bicarbonate and carbonate has stayed relatively constant, has the alkalinity of the ocean increased or decreased since the industrial revolution?
