Products Calcium oxide is available as a pure substance in pharmacies and drugstores. Structure and properties Calcium oxide (CaO, Mr = 56.08 g/mol) is the basic oxide of calcium. It exists as a white and odorless powder and reacts strongly with water (see below). It should therefore be stored away from moisture. It can be … Calcium Oxide
Products Bases are available as pure substances in pharmacies and drugstores. They are included in numerous medicines as active ingredients and excipients. Definition Bases (B) are proton acceptors. They accept a proton from an acid (HA), a proton donor, in the acid-base reaction. Thus, they lead to deprotonation: HA + B ⇄ HB + + … Bases
