Mg(OH)2 is a white powder. It is not very soluble in water. Mg(OH)2 is a weak base because its low solubility in water, also know as milk of magnesia, can be used to neutralize stomach acid. It can also be used as a laxative to treat occasional constipation.
Example Reactions:
• Mg(OH)2 = MgO + H2O
• Mg(OH)2 + 2HCl = MgCl2 + 2H2O
• Mg(OH)2 + 2HNO3 = Mg(NO3)2 + 2H2O
• 2HBr + Mg(OH)2 = MgBr2 + 2H2O
• Mg(OH)2 + H2SO4 = MgSO4 + 2H2O
• MgCl2 + 2NaOH = Mg(OH)2↓ + 2NaCl
• Mg + 2H2O = Mg(OH)2↓ + H2
• Mg(NO3)2 + 2NaOH = 2NaNO3 + Mg(OH)2↓
• 2KOH + MgSO4 = Mg(OH)2↓ + K2SO4
• Mg(NO3)2 + 2KOH = Mg(OH)2↓ + 2KNO3
