For which of the following is the Ksp value of the ionic compound the largest? The smallest? Explain your answer.
Answer to relevant QuestionsAg2S(s) has a larger molar solubility than CuS even though Ag2S has the smaller Ksp value. Explain how this is possible. For each of the following pairs of solids, determine which solid has the smallest molar solubility. a. CaF2(s), Ksp = 4.0 × 10-11 or BaF2(s), Ksp = 2.4 × 10-5 b. Ca3(PO4) 2(s), Ksp = 1.3 × 10-32 or FePO4(s), Ksp = 1.0 × ...Describe how you could separate the ions in each of the following groups by selective precipitation. a. Ag+, Mg2+, Cu2+ b. Pb2+, Ca2+, Fe2+ c. Cl-, Br-, I- d. Pb2+, Bi3+ Will a precipitate of Cd(OH)2 form if 1.0 mL of 1.0 M Cd(NO3)2 is added to 1.0 L of 5.0 M NH3? Cd2+(aq) + 4NH3(aq) ⇌ Cd(NH3)42+(aq) K = 1.0 × 107 Cd(OH)2(s) ⇌ Cd2+(aq) + 2OH-(aq) Ksp = 5.9 × 10-15 The copper(I) ion forms a complex ion with CN- according to the following equation: Cu+(aq) + 3CN-(aq) ⇌ Cu(CN)32-(aq) Kf = 1.0 × 1011 a. Calculate the solubility of CuBr(s) (Ksp = 1.0 × 10-5) in 1.0 L of 1.0 M NaCN. b. ...
