A. The K_sp for BaF_2 is 1.7 times 10^-6. What is the molar solubility of barium fluoride? b. Will PbSO_4, be more or less soluble in 0.1 M H_2SO_4 compared to in pure water? Why? Explain in terms of LeChatelier’s Principle. (This is from unit 6 and will be identical on the final) Sketch the pH sensitive glass electrode, label all parts, and indicate the function of each. a. Identify the ligands in the following complex ions. [Ni(CN)_4]^2- [Fe CDTA]^3+ b. How does the Fluoride lon-Selective Electrode it detect the fluoride ion? Include the species of fluoride that need to be considered, how to free the fluoride ion, and pH considerations.
