NaoH is called caustic soda.
KoH is called caustic pottash.
NaoH and KoH are called soda lime.
Ca(oH)2 is called slake lime.
CaCo3 is called limestone (which on dilution with water gives milkiness).
Conc. NaCl solution is called brine.
Cao is called QUICK LIME.

Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline crystalline solid at room temperature. The broadly used term "lime" connotes calcium-containing inorganic materials, which include carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate, such as limestone. By contrast, "quicklime" specifically applies to a single chemical compound.
