1. Calculate the pH of a buffer solution: a) Containing 0.015 M acetic acid and 0.035 M sodium acetate. b) The same solution as in part a) after enough HCl has been added to establish a Cl concentration of 0.001 M. Where: $K_A = 1.8 \times 10^{-5}$ 2. For the carbonate system in pure water, what species dominates at the typical pH encountered in natural water sources? 3. A sample of water collected in the field had a pH of 6.8. By the time it was analyzed in the lab, the pH had decreased to 6.0. Give a possible explanation. 4. For a water sample with a bicarbonate ion concentration of 50 mg/L and a CO2 content of 30 mg/L: a) Find the pH & b) Find the pH if CO2 is reduced by aeration to only 3 mg/L.
