Sodium bicarbonate, NaHCO₃, commonly known as baking soda, is dissolved in water at 10^–2 m at 298.15 K. Assume ideal solutions.

(a) Determine the pH and the dominant species concentrations. For this part of the problem, ignore the potential loss of CO₂ escaping from the solution as vapor.

(b) Now evaluate whether CO₂ may have a propensity to come out of solution at the conditions determined in (a) at 1 bar total pressure. y_CO2 = 0.0003 is the normal ambient value.
