SrCO3 is a sparingly soluble salt. Using the Ksp from the appendix, a) Determine the concentrations Sr2+ and CO32- when SrCO3 is dissolved in pure water ignoring secondary reactions of Sr2+ and CO32- and ignoring the activity from dissolved Sr2+ and CO32-. b) Using the concentrations of Sr2+ and CO32- found in a), determine the ionic strength of the solution, the activity coefficients of Sr2+ and CO32-, and account for these in a recalculated concentration of Sr2+ and CO32- (only one iteration of this calculated is expected). Continue to ignore reactions of Sr2+ and CO32-.
