Recent measurements of the melt-water from high-altitude snow in Green- land and the Himalayas have given pH values of 5.15 instead of the expected value. Some of this difference can be explained by the variation of the equi- librium constants as a function of temperature. a. Please calculate the pH of water at 0 °C in equilibrium with CO₂ at its current partial pressure. b. What would the partial pressure (in ppm) of CO₂ have to be in order to get precipitation of pH = 5.15 at this temperature? Note that at 0 °C PKH = 1.11, pKal = 6.57, and pK₁2 = 10.62. c. What do you conclude from part b? Recent measurements of the melt-water from high-altitude snow in Green- land and the Himalayas have given pH values of 5.15 instead of the expected value.
