(1) Magnesium carbonate 

(2) Sodium bicarbonate 

(3) Calcium hydroxide 

(4) Magnesium hydroxide 

Answer: (4) Magnesium hydroxide is an inorganic compound with the chemical formula Mg (OH)2. As a suspension in water, it is often called Milk of magnesia because of its milk-like appearance. The solid mineral form of magnesium hydroxide is known as brucite. Magnesium hydroxide is a common component of antacids and laxatives; it interferes with the absorption of folic acid and iron. Magnesium hydroxide has low solubility in water, with a Ksp of 1.5×10–11; however, all of the magnesium hydroxides that do dissolve dissociates.
