5) Dissolving of strontium precipitates - K overall -/2 points The following question refers to the sulfate test. In the first part of the sulfate test, a precipitate formed with strontium with both sulfate and sulfite. Then these precipitates will dissolve upon the addition of the acid added later in the test. Write out the overall reaction for the dissolving of the strontium precipitate upon the addition of the acid. This overall reaction can be generated by the combination of two different reactions. Using the provided constants here and any necessary constants from the CHEM_III_Eqn_Sheet, calculate the equilibrium constants for the overall reactions for both the sulfate and sulfite combination. Report your values here for the equilibrium constant for both the sulfate and sulfite combinations. Ksp of SrSO can be found in the Appendix of your text: OpenStax Solubility Products Ksp of SrSO₂ is 4 x 10-8 Overall Equilibrium Constant for SO Overall Equilibrium Constant for SO Evaluate
