Sodium silicate is a generic name for chemical compounds with the
The anions are often polymeric. These compounds are generally colorless transparent solids or white powders, and soluble in water in various amounts.
Sodium nitrate is the chemical compound with the formula NaNO3. This alkali metal nitrate salt is also known as Chili saltpeter (because large deposits of this salt can be found in Chile) to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter.
Sal ammoniac or Salammoniac, is a rare naturally occurring mineral composed of ammonium chloride, NH4Cl. It forms colorless, white, or yellow-brown crystals in the isometric-hexoctahedral class. It has very poor cleavage and a brittle to conchoidal fracture. It is quite soft, with a Mohs hardness of 1.5 to 2, and it has a low specific gravity of 1.5. It is water-soluble. Sal ammoniac is also the archaic name for the chemical compound ammonium chloride.
