Magnesium hydroxide is an inorganic compound with the chemical formula Mg (OH) 2. It occurs in nature as the mineral brucite. It is a white solid with low solubility in water ( Ksp = 5.61 × 10−12 ). [5] Magnesium hydroxide is a common component of antacids, such as milk of magnesia .
Its solubility product K sp of 5.02 × 10 −6 at 25 °C, its dissociation in water is large enough that its solutions are basic according to the following dissolution reaction: Ca(OH) 2 → Ca 2+ + 2 OH −. The solubility is affected by the common-ion effect. Its solubility drastically decreases upon addition of hydroxide or calcium sources.
Dissolution testing. In the pharmaceutical industry, drug dissolution testing is routinely used to provide critical in vitro drug release information for both quality control purposes, i.e., to assess batch-to-batch consistency of solid oral dosage forms such as tablets, and drug development, i.e., to predict in vivo drug release profiles.

Hydroxide is a diatomic anion with chemical formula OH −. It consists of an oxygen and hydrogen atom held together by a single covalent bond, and carries a negative electric charge. It is an important but usually minor constituent of water. It functions as a base, a ligand, a nucleophile, and a catalyst.
The solution was initially prepared at 20 °C and then stored for 2 days at 4 °C. In chemistry, solubility is the ability of a substance, the solute, to form a solution with another substance, the solvent. Insolubility is the opposite property, the inability of the solute to form such a solution. The extent of the solubility of a substance in ...
The Ohio House of Representatives is the lower house of the Ohio General Assembly, the state legislature of the U.S. state of Ohio; the other house of the bicameral legislature being the Ohio Senate . The House of Representatives first met in Chillicothe on March 3, 1803, under the later superseded state constitution of that year.
