At 25 °C, the base ionization constant for NH
3 is 1.8 × 10
–5. If 0.0800 mole of solid magnesium chloride is dissolved in a solution prepared by adding 0.0500 mol of solid ammonium chloride to 100. ml of 0.150 M ammonia, will a precipitate of magnesium hydroxide form? (Assume the volume of the solution is unchanged. The solubility product constant for magnesium hydroxide is 1.5 × 10
–11.)
