Answer
It forms a salt and water when reacting with acids.
Explanation
The cause is that magnesium hydroxide reacts with acids. The mechanism involves the neutralization reaction where magnesium hydroxide, a base, reacts with hydrogen ions from the acid to form magnesium salts and water. The effect is the reduction of acidity in the solution, which is beneficial for treating indigestion. Consequently, it is used in antacid formulations.
Common mistake
Misunderstanding Barium Sulfate's Safety
Students often believe that barium sulfate is safe to use in medicine because it is a barium compound, overlooking its toxicity.
Barium sulfate is used in medicine because it is insoluble in water, preventing it from being absorbed into the bloodstream, thus minimizing toxicity while allowing it to be used as a contrast agent in medical imaging.
