Unformatted text preview: 6. When the strong base is added to account for exactly half of the moles of the weak acid, describe the components that would be present in solution. 7. When the strong base is added to account for all of the moles of the weak acid, describe the components of the solution. 8. Make a prediction for pH in question 7: 9. Which question above (5, 6 or 7) describes the equivalence point of the titration? 10. Which question above (5, 6 or 7) describes the buffer region of the titration? 19.2 Solubility 11. What is the concentration of Zn 2+ if 5528.4 g of ZnCO 3 are added to 125 L of water? K sp (ZnCO 3 ) = 1.0 * 10-10 12. Write a dissociation reaction for BaF 2 and solve for [F ]. K sp (BaF 2 ) = 1.5 * 10-6 13. Given that K a (HF) = 6.8 * 10 4 , solve for the pH of the solution in question 12....
