Calcium hydroxide - Wikipedia

Ca(OH) 2 → Ca 2+ + 2 OH −. At ambient temperature, calcium hydroxide (portlandite) dissolves in pure water to produce an alkaline solution with a pH of about 12.5. Calcium hydroxide solutions can cause chemical burns. At high pH value due to a common-ion effect with the hydroxide anion OH −, its solubility drastically decreases.
