What are the products for the reaction of magnesium hydroxide with water? \( \mathrm{Mg}^{2+}(a q)+2 \mathrm{OH}^{-}(a q) \) \( \mathrm{H}_{2}(g)+\mathrm{MgO}(s)+\mathrm{O}_{2}(g) \) \( \mathrm{Mg}(s)+\mathrm{OH}(a q) \) \( \mathrm{Mg}^{2+}(a q)+\mathrm{OH}_{2}^{-}(a q) \)

When magnesium hydroxide interacts with water, it does not create new products like gases or solids; instead, it typically dissociates into its ions. Mostly, you would find magnesium ions and hydroxide ions in solution, reflecting its basic nature. In real-world scenarios, magnesium hydroxide is often utilized as an antacid to neutralize stomach acid, helping alleviate indigestion and heartburn. The subsequent reaction in the stomach can lead to the formation of magnesium salts, offering a soothing effect while improving digestion, which showcases practical chemistry in everyday health!
