Normally, in everyday language, when they say the word “salt,” they are referrring to table salt, sodium chloride. But you may have heard of “epsom salts.”
So what is a salt? A salt is a substance that consists of a postive ion other than H+ and a negative ion other than OH-. Examples of salts that are found in the body are sodium chloride (NaCl), calcium carbonate (CaCO3), and potassium chloride (KCl).
When an acid interacts with a base, a salt is formed. For instance, if you combined hydrochloric acid (HCl) and sodium hydroxide (NaOH), you get sodium chloride (NaCl) and water.
HCl + NaOH –> NaCl + H2O
