Theory Quote by Sam Kean
““Acid strength is measured by the pH scale, with lower numbers being stronger, and in 2005 a chemist from New Zealand invented a boron-based acid called a carborane, with a pH of -18””
About This Quote
Source Book: The Disappearing Spoon, Sam Kean, 2010
Acid strength is indicated by pH; lower values mean stronger acids, and a synthetic boron acid can have a negative pH.
In simple terms: pH shows acidity; lower = stronger; a lab‑made acid can be extremely strong.
Key Takeaway
Recognize that pH can go below zero for super‑strong acids.
