A sample of solid Eu(OH)3 was stirred in water at a certain temperature until the solution contained as much dissolved Eu(OH)3 as it could hold. A 650-mL sample of this solution was withdrawn and titrated with 1.33e-05 M HBr. It required 21 mL of the acid solution for neutralization. What is the solubility of Eu(OH)3 in water, at the experimental temperature, in grams of Eu(OH)3 per liter of solution? a) The solubility is 7.06e-10 g/L. b) The solubility is 8.72e-05 g/L. c) The solubility is 0.000262 g/L. d) The solubility is 2.91e-05 g/L. e) The solubility is 6.08e-06 g/L.
