Sodium chloride /ˌsoʊdiəm ˈklɔːraɪd/, commonly known as salt (although sea salt also contains other chemical salts), 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
Diffusible calcium | Article about diffusible calcium by …
Today, calcium metal is usually prepared by electrolysis of fused calcium chloride to which a little calcium fluoride has been added. It is used in alloys with other metals, such as aluminum, lead, or copper; in preparation of other metals, such as thorium and uranium, by reduction; and (like barium) in the manufacture of vacuum tubes to remove residual gases.

The lattice spacing of the face-centre cubic solid solution varies almost linearly with atomic concentration between the values for copper (3.6153 . 10-8 cm) and that for nickel (3.5238 . 10-8 cm). Cu-Ni alloys are alloys of copper (base metal with the largest individual content) and nickel with or without other elements, whereby the zinc content may not be more than 1%.

COBALT CHLORIDE - Molecule of the Month June 2016 - …
The colour of transition metal complexes is due to electronic transitions between different d-orbitals. Water produces larger splittings between the energy levels than chloride (H 2 O is a ‘stronger-field’ ligand than Cl) so the energy differences between different electronic energy levels are smaller in complexes with lots of chlorides as ligands, so this has a significant effect on the
