QUESTION:

(a) Describe a preparation for magnesium hydroxide [Mg(OH)2] and predict its solubility. (b) Milk of magnesia contains mostly Mg(OH)2 and is effective in treating acid (mostly hydrochloric acid) indigestion. Calculate the volume of a 0.035 M HCl solution (a typical acid concentration in an upset stomach) needed to react with two spoonfuls (approximately 10 mL) of milk of magnesia [at 0.080 g Mg(OH)2/mL].
