At 25 C, the base ionization constant for NH3 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, a precipitate of magnesium hydroxide will form. (Assume the volume of the solution is unchanged. The solubility product constant for magnesium hydroxide is 1.5 * 10-11.)
