A lake of 1000 m3 is receiving acid mine drainage at a rate of 10 m3 / day. The AMD water contains Fe3 and SO4 2- at 5.0 mmol/L and 12.0 mmol/L, respectively. The pH of the AMD is 3.0. The original lake water is at a pH of 8.0 and contains Fe3 and SO4 2- at 0.02 mmol/L and 0.04 mmol/L. Assume the lake is well-mixed and its outflow rates are the same as inflow. Please calculate the following: 1) (6 points) What are the pH, Fe3 and SO4 2- at the outflow after 10 days of receiving the AMD water
