Calcium chloride - Wikipedia

Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white coloured crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide. Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl2(H2O)x, where x = 0, 1, 2, 4, and 6. These compounds are …

The Ionic Bond | Boundless Chemistry - Lumen Learning

The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or ion. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion. One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom.
