4) Using the Davies equation, calculate the effect of ionic strength alone on the solubility of gypsum as you go from a very dilute, ideal solution to a NaCl solution with I= 0.5. Here we can express the solubility as the product of the concentrations of total calcium times sulfate or [Ca"][So]. Assume no ion pair species form. CaS04-2H20 = Ca+S0+2H20 K = 2.4x105
