Groundwater Flow

The term groundwater refers to the water which is found beneath the earth's surface. Pores present in the soil and rocks with fractures make a passage for rainwater to enter the earth's surface and deposit as groundwater. The flow nature and direction of groundwater under the earth's surface directly impacts the strength and compressibility of the soil, which reflects its ability to support structural loads.

Question

1.
(a) Groundwater at 10°C equilibrates with calcite (CaCO,) in an atmosphere that has a CO, partial
pressure of 101 atm. What is the pH, [Ca"), total alkalinity and [HCO,] of the groundwater?
(b) If a sample of the water in part (a) is equilibrated with Pco2 = 1035 atm and CaCco, how much
Caco; precipitates (or dissolves)? What is the new pH, [Ca"], total alkalinity and [HCO, ]?
