Calcium hydroxide | Ca(OH)2 - PubChem

Pure calcium hydroxide paste has a high pH (approximately 12.5-12.8) and is classified chemically as a strong base. Its main actions are achieved through the ionic dissociation of Ca (2+) and OH (-) ions and their effect on vital tissues, the induction of hard-tissue deposition and the antibacterial properties.

Iron corrosion products

Only iron and steel rust. Other metals corrode. Rusting is an oxidation process. What we normally call rust is a flaky red-brown solid which is largely hydrated iron.The primary corrosion product of iron is Fe(OH)2 (or more likely FeO.nH 2 O), but the action of oxygen and water can yield other products having different colors:
