Acids, Bases, and Salts
Acids and bases are all around us, including a diverse array of food, drink and domestic products, providing many opportunities to explore real contexts and applications of chemistry. Note though, the over-exaggerated portrayal of acids in the media (like movies and TV shows) can be unhelpful. While acids often are highly corrosive substances that ‘eat away’ materials in their path – some bases are even more corrosive. But, bases don’t share the reputation of their acidic counterparts in movies (for example). Further – salt is more than just table salt (sodium chloride, NaCl) used for food. Salt is any chemical compound formed from the reaction of an acid with a base.
