Sodium chloride Sodium chloride Sodium chloride , also known as salt (though 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. Sodium chloride is the salt most responsible for the salinity of seawater and of the extracellular fluid of many multicellular organisms. In its edible form of table salt, it is commonly used as a condiment and food preservative. Large quantities of sodium chloride are
Chemical compound microarray Polymer microarrays have been developed to allow screening for new polymeric materials to direct different tissue lineages. Research has also been directed towards studying the surface chemistry of these arrays to determine which surface chemistries control cell adhesion, although concerns have been raised as to the influence of the substrate on measurements and the questionable statistical interpretation of results. The lack of control in the production of many of these polymer arrays suggests that any practical application of these technologies will be limited. This is particularly true for the in situ polymerisation of acrylate monomers in minute volumes. Chemical compound
