Calcium chloride is a salt that is marketed in pellet form for removing dampness from rooms. Remarkably hydroscopic, it is placed in perforated containers or on screens with a containers below them. Calcium chloride will collect enough water from the air to completely transform the pellets, leaving an empty basket and a volume of solution below it which is several times the volume of the
Sodium chloride | Wikipedia Encyclopaedia Wiki | Fandom
Sodium chloride, also known as salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl. Sodium chloride is the salt most responsible for the salinity of seawater and of the extracellular fluid of many multicellular organisms. In its
