The concentration of dissolved O2 in water that is required to support aquatic life is 4.0 mg/L. Calculate the minimum partial pressure of oxygen (in kPa) in the atmosphere that is required to achieve this concentration. (Use kH= 1.30 x 10-2 mol m-3 kPa-1)
At the Oak Ridge National Laboratory in Tennessee, soils are heavily contaminated with mercury (Hg*2). In some of the soils, sulfate-reducing bacteria are producing bisulfide (HS). In these soils, mercury precipitates with sulfide to form metacinnabar (HgS(s). HgS +H" Hg +HS (3), a. What is the equilibrium constant for this reaction? Assume a temperature of 25 °C. b. What is the effective equilibrium constant for an ionic strength of 0.01 M (call it Kegeff)? Use the Davies equation to make the calculation
Sodium tripolyphosphate (Na,P,O10) is used in many syn- thetic detergents. Its major effect is to soften the water by complexing Mg?+ and Ca+ ions. It also increases the effi- ciency of surfactants, or wetting agents that lower a liquid's surface tension. The K value for the formation of MgP,O, is 4.0 x 10%. The reaction is Mg*(aq) + P,O,, (aq) = MgP,O1, (aq). Calculate the concentration of Mg* in a solution that was originally 50. ppm Mg?+ (50. mg/L of solution) after 40. g Na,P,O10 is added to 1.0L of the solution.
