A sample of water from Lake Huron has a pH of 7.34 and an alkalinity of 1.21 mmol L-1 as calcium carbonate. Assume equilibrium with the calcium carbonate in the sediment and calculate the concentration of calcium ion (in mg/L -1) in the water (25C). What assumptions are made in carrying out the calculation? Please show all work.
