Just venting: acusd.edu You are my assistant aboard the Ocean Drilling Program research vessel, JOIDES Resolution. Your job is to measure pH, Fe+2 and H2S concentrations in hydrothermal vent fluids. Your measured data are: [Fe+2] = 0.05 mM/l [H2S ] = 26.9 mM/l pH = 5.6 Fe+2 and H2S data are reproducible and reasonable, but your pH meter has not been working well and your pH data is suspect. You need an alternate way to verify pH data. Your handy biogeochem text tells you that pyrrhotite (FeS) forms according to the following equation: Fe+2 + H2S = FeS + 2H+ Log Ksp = -2.28 M/l Brassy yellow sulfides are abundant in the hydrothermal vent wall rocks, and the X-ray diffraction technician tells you that the mineral is pyrrhotite (not pyrite). It may be safe to assume that [Fe+2] is pyrrotite solubility controlled. Calculate the expected pH of the fluid from the concentration data you have at hand. Is your measured pH reasonable? step 1. Put all concentrations into uits of M/l [Fe+2] = (0.05mM/l)(1mM/1000mM)(1M/1000mM) = 5 X 10-8 M/l [H2S ] = (26.9mM/l)(1M/1000mM) = 2.69 X 10-2 M/l step 2. Set up the Ksp calculation with [H+] as the unknown, since [H+] with give you pH. Remember that for solids, in this case FeS, the concentration is 1, and that coefficients, such as 2H+ in this case, become exponents of the concentrations, [H+]2. Ksp = [products] [reactants] 10 -2.28M/l = [FeS][H+]2 [FeS] = 1 [Fe+2][H2S] [H+] = square root of {(10 -2.28)(5 10-8)(2.69 10-2)} [H+] = 2.657 10 -6 M/l pH = negative log of the [H+], and the neg log of 2.657 10 -6 = 5.6, so pH = 5.6 Your pH meter is working properly!

no no Thor, a philosophy doc tells what is what, not who is who. first what is what then how is how then who is who you missed the first 2 steps no wonder this thread is in the DogHouse we shareholders want to know Who is selling & buying we know what, its gpgi shares the How is a mystery a Who leads to a How, then a What as in What The **** is happening i hope it ain't going to be How E Duty Time i never did like that show of long ago was it Buffalo Bill or Buffalo Bob Oops, sorry Bob amazing all it would take is a simple official gpgi release from Jensen either (1) update updateD (1a) GPGI has NO idea whats causing the high volumn & low share price (1b) Its TRUE, Mr Jensen does NOT care what the gpgi share price is (2) New update (2a) ignore last update (2b) NO Comment (2c) -end of update- doug
