compounds with limited solubility. You are only supposed to consider the limited solubility of the compounds that the question mentions. Barium fluoride BaF2 has limited solubility. We prepare a saturated solution of barium fluoride, with precipitate left at the bottom. What happens when... - We add sodium chloride solid, the solution (1/2/3) therefore - We add few drops of concentrated nitric acid, the solution (1/2/3) therefore - We dissolve some sodium hydroxide solid, the solution (1/2/3) therefore Possible answers: 1: becomes momentarily unsaturated 2: 1 comes momentarily supersaturated 3: ci s not change 4: more precipitate forms 5: more precipitate dissolves 6: nothing happens In this problem you are expected to remember the acid/base character of substances, but not the compounds with limited solubility. You are only supposed to consider the limited solubility of the compounds that the question mentions. Iron (III) hydroxide Fe(OH)3 has limited solubility. We prepare a saturated solution of iron (III) hydroxide, with precipitate left at the bottom. What happens when... - We add few drops of concentrated hydrochloric acid, the solution therefore (4/5/6) (1/2/3) - We dissolve some solid iron(III) chloride FeCl3, the solution therefore (4/5/6) (1/2/3) - We add a saturated solution of iron (III) hydroxide Fe(OH)3, the solution (1/2/3) therefore (4/5/6) Possible answers: 1: becomes momentarily unsaturated 2: becomes momentarily supersaturated 3: does not change 4: more precipitate forms 5: more precipitate dissolves 6: nothing happens The molar solubility of lead(II) fluoride (PbF2) is 2.1103mol/L in pure water at 25C. What is the molar solubility of lead(II) fluoride in 0.10MNaF at 25C ? (Assume that the only relevant reaction is the solubility-product equilibrium.) 2.1101mol/L 2.1103mol/L 4.4105mol/L 3.7106mol/L The Ksp of a salt MX3 is 6.4E3. . " M " is the metallic cation and " X " the non-metal anion. How many moles of the metal anion " M " will be dissolved in 70 liters of a saturated solution of MX3 ? Give your answer with at least two decimal points
