A 0.6025 g sample was dissolved, and the Ca2+ and Ba2+ ions present were precipitated as BaC2O4·H2O and CaC2O4·H2O. The oxalates were then heated in a thermogravimetric apparatus leaving a residue that weighed 0.5713 g in the 320o-400oC range and 0.4673 g in the 580o-620oC range. Calculate the percentages of Ca and Ba in the original sample.

Hard water often contains dissolved Ca2+ and Mg2+ ions. One way to soften water is to add phosphates. The phosphate ion forms insoluble precipitates with calcium and magnesium ions, removing them from solution. Suppose that a solution is 0.049 M in calcium chloride and 0.094 M in magnesium nitrate. What mass of sodium phosphate would have to be added to 1.4 L of this solution to completely eliminate the hard water ions? Assume complete reaction. Enter a numerical answer in...

Use solubility rules and other properties to separate the given ions (Ba2+, Ag+, and Fe3+) Ba2+, Ag+, and Fe3+ mixed in one beaker. Real compounds dissolved: Ba(NO3)2, AgNO3 and Fe(NO3)3; 0.1 mol/L for all. You may need to precipitate them one by one. HNO3, NaI, Na2SO4, NaOH, NaHCO3, Na2CO3, Na3PO4, filter paper, funnel, and Erlenmeyer flasks are available to accomplish the task. Three solid samples total should be obtained. What is a procedure for separating the given ions?
