What is the chemical name of milk of magnesia?

Correct option is B

The correct answer is (b) Magnesium hydroxide.
· Milk of magnesia is the common name for a suspension of magnesium hydroxide (Mg(OH)₂) in water.
· It is primarily used as an antacid to neutralize stomach acid and as a laxative to relieve constipation. The "milk" term comes from its milky-white appearance.
· It is a mild and safe over-the-counter remedy, often used in small doses.
Additional Information:
· Ammonium hydroxide : This is commonly known as ammonia in water, not related to milk of magnesia.
· Calcium hydroxide : Also known as slaked lime, it is used in construction and water treatment, not as an antacid.
· Sodium hydroxide : Also known as caustic soda, it is a strong base used in industrial processes, not as a remedy for indigestion.
