Question

student question: 75 mL, of water and 0.10 moles of CO.(g) are added to a on vessel at 25 °C. A) What concentration of CO.(aq) do you expect to find at equilibrium? Henry's law constant-2 4x102 mol/L atm (12 pts) I mal-o B) Modified student question: If all the dissolved Co.(aq) reacts fully with water, then what is the pH of the water after equilibrium is reached? H2CO3 Kal = 4.2x10", Ka2-4.8×10-11. (12 pts) C) If you add CaCl2 to the reaction vessel, what do you expect to happen to the concentration of CO (aq)? EXPLAIN how the pH of the solution will change. Include all relevant reactions. (8 pts)
