The One Where We Put Stuff in Acid

Reactions is a show that uncovers the chemistry all around us. We answer the burning questions you’ve always wanted to ask, blending the worlds of science and every-day life.

Season 4 Episode 38 | 5m 13s

Watch as Reactions uses some acid know-how to tell a chemistry detective story and sort real gold from the imposters. Acids are reactive, and even weak acids like vinegar can wow people with their reactivity. But strong acids can really put on a show, dissolving otherwise relatively inert metals. And aqua regia, or royal water, is a mixture of hydrochloric and nitric acids that can dissolve gold.
