Common salt: A vital Ingredient - the story

Synopsis

Common salt, or Sodium chloride (NaCl) has a rich history and numerous technical applications, Sodium and Chlorine are abundant elements in the earth's crust and oceans. Historically, salt was a valuable commodity, leading to significant trade routes and financial importance. Salt is estimated to have over 14,000 uses and its vital roles include food manufacturing, pharmaceuticals, road gritting, seasoning and water softening. It is one of the largest-volume inorganic raw materials used by the chemical industry. The lecture will illustrate the story of salt from its geological formation, its extraction from sea water and mining operations, the whole spectrum of the uses, including its importance to life, and the whole variety of manufacturing processes where salt is the vital raw material.

This lecture will be given by Dr Fred Parrett (former Chair of SCI’s London Regional Group and currently Treasurer).  We hope you will join us for the reinstatement of this Christmas lecture series which will be followed by a drinks and mince pie reception.
