Being the product of a neutralization reaction between an acid and a base, sodium chloride is neutral, with a pH of seven. Sodium chloride is an ionic compound with the chemical formula NaCl.
Sodium chloride is also known as common table salt. It is used as a food condiment, a food preservative, a catalyst for chemical production, a water softener and a de-icer. Sodium chloride is highly soluble in water. Sea water by weight consists of 2.7 percent sodium chloride. When dissolved in water, sodium chloride becomes a conductor of electricity. By running a current through a solution of sodium chloride and water, it can be decomposed into atoms of sodium and chlorine.
