Nitric acid (HNO) greatly enhance the rate of reaction. Although chromium (Cr), iron (Fe), and aluminium (Al) readily dissolve in dilute nitric acid, the concentrated acid forms a metal-oxide layer that protects the bulk of the metal from further oxidation. The formation of this protective layer is called passivation. Typical passivation concentrations range from 20% to 50% by volume (see ASTM A967-05). Metals that are passivated by concentrated nitric acid are iron, cobalt, chromium, nickel, and aluminium. Being a powerful oxidizing acid, nitric acid reacts violently with many organic materials and the reactions may be explosive. The hydroxyl group will typically strip
The Electric Kool-Aid Acid Test a--Wolfe’s a genius. He did a lot of that stuff, he was only around three weeks. He picked up that amount of dialogue and verisimilitude without tape recorder, without taking notes to any extent. He just watches very carefully and remembers. But, you know, he’s got his own editorial filter there. And so what he’s coming up with is part of me, but it’s not all of me. . . .” The Electric Kool-Aid Acid Test The Electric Kool-Aid Acid Test is a nonfiction book by Tom Wolfe that was published in 1968. The book is remembered today as an
