When 12.0 mL of a 7.13 × 10-4 M manganese(II) iodide, MnI2, solution is combined with 22.0 mL of 5.17 × 10-4 M potassium hydroxide, does a precipitate form? (Ksp for manganese(II) hydroxide is 4.6 x 10-14) Group of answer choices The solution is unsaturated – no precipitate forms The concentration of iodide ions is reduced by the addition of OH− ions The presence of KOH will raise the solubility of MnI2 One must know Ksp for MnI2 to make a prediction Mn(OH)2 will precipitate until the solution becomes saturated
