Saltpeter is the common name used for several different chemical compounds, specifically for potassium nitrate and sodium nitrate. Potassium nitrate is commonly used in gunpowder, and sodium nitrate is found in fertilizers and explosives.
The word Salt in English often means 'table salt' or 'edible salt' (which is salt that can be eaten). This kind of salt is made up mostly of sodium chloride (NaCl). It is one of the few minerals that are eaten a lot by humans, but it can be used for other things besides giving food its flavor.
