- The Debye-Hückel Theory and the Güntelberg and Davies Approximations are not accurate for very high ionic-strength solutions like seawater. Thus, more complicated methods must be used to calculate activity coefficients in seawater, or they can be determined experimentally. One study reported the following activity coefficients: Chemical Species Activity Coefficient (y) Ca2+ 0.28 CO32- 0.20 CaCO3 1.13* For a seawater sample with 140 µM Ca 2+ and 210 μM CO32-, let's determine if precipitation of CaCO3 is thermodynamically favorable: A) If you ignored the effect of the salinity on the activities of all the chemical species, what would be the value of Q? Based on this value of Q, would you expect CaCO3 to precipitate? B) Considering the activity coefficients given in the table above, what would be the value of Q (IAP)? Based on this value of Q (IAP), would you expect CaCO3 to precipitate?arrow_forwardThe Jeffersonville Transportation Study area has been divided into four traffic zones.
