What is the maximum molarity of PO43- in a solution that contains 0.20 M Co2+?   For Co3(PO4)2  Ksp = 2.5 x 10-5

The molar solubility of Pb (103)₂ Be sure your answer has the correct number of significant digits. K₂-1 -0 sp in a 0.21 M NalO3 solution is 3.8 x 10 X 11 mol L What is Ksp for Pb (103)₂?

11b.

Calculate the initial concentration of Fe3+, based on the dilution that results from adding KSCN solution and water to the original 0.0020 M Fe(NO3)3solution. See Step 2 of the procedure for the volume of each substance used in Test Tubes 1-4. This value will be the same value for all four test tubes. This is essentially the same as filling out part of the “I” row in an ICE table. Test tube number 0.0020 M Fe(NO3)3(mL) 0.0020M KSCN(mL) H2O(mL) 1 5 2 3 2 5 3 2 3 5 4 1 4 5 5 0

1. Determine the mass of CaCl2·2H2O (MW 147.02 g/mole) to weigh out using a four- place analytical balance to prepare 100 mL of a 0.1005 M solution of Ca2+. 2. Determine the mass of KCI to weigh out using a four-place analytical balance to prepare 100 mL of a 1 M solution of KCI (MW 74.5513 g/mole). 3. Record the solubility of calcium carbonate in water (mg/L) in your notebook. 4. Calculate the amount of calcium carbonate (mg) not in solution if a tablet is dissolved in 250 mL of water and the tablet's label claim is 600 mg calcium / tablet.
