1- Copper (II) oxalate (CuC₂O₄) is a sparingly soluble salt with Ksp=4.43×10-10. Cupric ions (Cu²⁺) form a complex with excess oxalate ions in solution according to the following equation:

Cu²⁺(aq)+2C₂O₂-4(aq)?[Cu(C₂O₄)²]²-(aq)

The Kf for this reaction is 1.7×1010. What is the molar solubility of CuC₂O₄ in a 0.10 M Na₂C₂O₄ solution?

2- A solution is prepared that is 0.500 M cyanoacetic acid ( HC3H2NO2) and 0.500 M in sodium cyanoacetate (NaC3H2NO2). What is the final pH of the solution after 0.300 moles of NaOH are added? The (Ka) of cyanoacetic acid is (3.39×10-3). Assume the change in volume is negligible.
