Solubility Homework Problem Set
This problem set was developed by S.E. Van Bramer for Chemistry 146 at Widener University.
- Assuming the molar solubility of a salt is x, write the balanced chemical equation for dissolving the solid salt, write the Ksp expression for the reaction, and rearrange the Ksp expression to solve for x.
- AB (s)
- AB2 (s)
- A2B (s)
- AB3 (s)
- A2B3 (s)
- 3.2 x 10-3 g of manganese (II) hydroxide will dissolve in 1 liter of water at 25 oC. What is the pH of a saturated manganese (II) hydroxide solution? What is Ksp for manganese (II) hydroxide?
- How many grams of silver chromate can dissolve in 250 mL of 0.25 M sodium chromate?
- 0.500 grams of lead nitrate is dissolved in 250.0 mL of water. When 10 mL of 1.0 M NaCl is added to this solution: What is the mass of the precipitate? What is the equilibrium concentration of all the ions in the solution? Repeat these calculatons if 20 mL of 2.0 M Na Cl is added to the original lead nitrate solution.
