The chemical formula for table salt is NaCl. Also called sodium chloride, natrium chloride or halite, table salt is an ionic compound that contains a positively charged ion of sodium and a negatively charged chloride ion connected through an ionic bond. Table salt appears as a white crystalline powder or colorless, transparent crystals, and it is one of the most commonly used salts.
Table salt is a product of the chemical reaction between hydrochloric acid and sodium hydroxide. This reaction is written as follows: HCl + NaOH → NaCl + H2O
Table salt is insoluble in hydrochloric acid and very slightly soluble in ammonia. It only takes 2.6 milliliters of boiling water to dissolve one gram of salt, according to data from the National Institutes of Health.
