Please finish the rest. I will also award you the best answer of the other question, which means 18$.

1. Write the ionic equation for dissolution and the solubility product (Ksp) expression for each of the following slightly soluble ionic compounds: (a) PbCl2 (b) Ag2S (c) Sr3(PO4)2 (d) SrSO4 2. You are provided with the solubilities of the following compounds in grams per 100 mL of water. Because these compounds are only slightly soluble, assume that the volume does not change on dissolution and calculate the solubility product for each. (a) BaSiF6, 0.026 g/100 mL (contains SiF62 ions) (b) Ce(IO3)4, 1.5 10-2 g/100 mL (c) Gd2(SO4)3, 3.98 g/100 mL (d) (NH4)2PtBr6, 0.59 g/100 mL (contains PtBr62 ions) 3. Perform the following calculations: (a) Calculate [Ag+] in a saturated aqueous solution of AgBr. (b) What will [Ag+] be when enough KBr has been added to make [Br-] = 0.050 M? (c) What will [Br-] be when enough AgNO3 has been added to make [Ag+] = 0.020 M? 4. Assuming that no equilibria other than dissolution are involved, calculate the concentrations of ions in a saturated solution of each of the following (see link above for solubility products). (a) TlCl (b) BaF2 (c) Ag2CrO4 (d) the mineral anglesite, PbSO4 5. Which of the following compounds precipitates from a solution that has the concentrations indicated? (See link above for Ksp values.) (a) KClO4: [K+] = 0.01 M, [ClO4] = 0.01 M (b) K2PtCl6: [K+] = 0.01 M, [PtCl62] = 0.01 M (c) PbI2: [Pb2+] = 0.003 M, [I-] = 1.3 10-3 M (d) Ag2S: [Ag+] = 1 10-10 M, [S2-] = 1 10-13 M 6. Which of the following compounds precipitates from a solution that has the concentrations indicated? (See link above for Ksp values.) (a) CaCO3: [Ca2+] = 0.003 M, [CO32] = 0.003 M (b) Co(OH)2: [Co2+] = 0.01 M, [OH-] = 1 10-7 M (c) CaHPO4: [Ca2+] = 0.01 M, [HPO42] = 2 10-6 M (d) Pb3(PO4)2: [Pb2+] = 0.01 M, [PO43] = 1 10-13 M Scanned by CamScanner Scanned by CamScanner Scanned by CamScanner Scanned by CamScanner Scanned by CamScanner Scanned by CamScanner Scanned by CamScanner Scanned by CamScanner
