The pH of a 25 degree celcius groundwater containing 10^-4M of Mg²⁺ is initially raised to 12. No further base is added. What will be the equilibrium pH and Mg²⁺ concentration? Assume that no carbonate species and no other ions are present that could precipitate and that Mg²⁺ precipitates as Mg(OH)_2(s). Recall that for every one Mg²⁺ that precipitates, two OH^- ions precipitate.

A groundwater containing 10-4 M of Mg2+ is at equilibrium. Use the solubility constant Ksp = 1.35 x 10^-11. Assuming no other ions are present, (a) what is the equilibrium pH,

(b) will Mg2+ precipitate if the pH is increased to 12 (show calculations)?

Water in an unconfined aquifer at a pressure of 1 atm and a temperature of 250C has a pH of 7.2 and a dissolved oxygen concentration, (O2)aq, of 0.016 mg/L (1.6 x 10-5 g/L). Several reactions relevant to this groundwater system are listed below with the corresponding equilibrium constants:

A. O2(g) = O2(aq) K = 10-2.89 mol/L-atm

B. ¼ O2(g) + H+ + e- = ½ H2O K = 1020.75

C. ½ NO3- + H+ + e- = ½ NO2- + ½ H2O K = 1014.15

D. H2O = H+ + OH- K = 10-14.0

a) Assuming that the redox system is at equilibrium, what is the pe of the groundwater?

b) For this pe and if [NO3 -] = 1.5 x 10-4, what is [NO2 -]?

The following graph shows the economy in long-run equilibrium at the expected price level of 120 and the natural rate of output of $600 billion. Suppose firms become pessimistic about future business conditions and cut back on investment spending.

Shift the short-run aggregate supply (AS) curve or the short-run aggregate demand (AD) curve to show the short-run impact of the business pessimism.

In the short run, the decrease in investment spending associated with business pessimism causes the price level to-------------- the price level people expected and the quantity of output to ---------------- the natural rate of output. The business pessimism will cause the unemployment rate to------------ the natural rate of unemployment in the short run.

Again, the following graph shows the economy in long-run equilibrium at the expected price level of 120 and the natural rate of output of $600 billion, before the decrease in investment spending associated with business pessimism.

Now show the long-run impact of the business pessimism by shifting both the short-run aggregate demand (AD) curve and the short-run aggregate supply (AS) curve to the appropriate positions.

In the long run, as a result of the business pessimism, the price level --------------- , the quantity of output------------ the natural rate of output, and the unemployment rate---------------- the natural rate of unemployment.
