Sodium carbonate

== Description ==
White, odorless crystals. Sodium carbonate has three distinct hydrated forms. The monohydrate is commonly called sodium carbonate while anhydrous sodium carbonate is called soda ash, and sodium carbonate decahydrate is called sal soda, or natron. Anhydrous sodium carbonate occurs in nature as the mineral thermonatrite. It forms a strongly alkaline aqueous solution and is used in the manufacture of leather and paper. Sodium carbonate is used as an ingredient in some types of glass, detergents, bleaches, and water softeners. It is also used in photographic developing baths and textiles dye baths.

Sodium carboxymethyl cellulose

== Description ==
A colorless, odorless, water-soluble polymer. Sodium carboxymethyl cellulose, NaCMC or CMC, was first developed in 1947. Commonly known as carboxymethyl cellulose, it is composed of the sodium salt of an alkaline modified cellulose. CMC is water-soluble but will react with heavy metal salts to form films that are clear, tough and insoluble in water. It is thixotropic, becoming less viscous when agitated. In most cases, CMC functions as a polyelectrolyte. It is used commercially in detergents, food product and as size for textiles and paper. In conservation, CMC has been used as an adhesive for textiles and paper. Aging studies indicate that most carboxymethyl cellulose (CMC) polymers have very good stability with negligible discoloration or weight loss (Feller and Wilt 1990).

Sodium chloride

== Description ==
Colorless, cubic crystals that naturally occur in ocean water at concentrations of 2.6% and as the mineral halite. Sodium chloride is obtained by evaporation of brines (sea salt) and by mining underground and surface deposits of halite (rock salt). Sodium chloride is widely used in food products for flavoring and preservation (see table salt). It is used for curing hides and skins prior to transportation or storage. Sodium chloride is also used in electrochemical reactions and as an assistant in mordanting. In a closed environment, a saturated solution of sodium chloride will maintain a relative humidity of about 75% (20C). In photography, sodium chloride is used in the precipitation of photographic emulsions, in reducing and toning solutions and as a washing aid to eliminate residual thiosulfate from silver images.

Single crystals of sodium fluoride are used as ultraviolet and infrared transmitting windows in scientific instruments. It is also used as a flux for ceramic glazes and glass. Aqueous solutions are used to etch glass since sodium fluoride forms hydrofluoric acid when dissolved in water.
