What’s the strongest base in the world?

A base is any substance that can accept a hydrogen ion – otherwise known as a proton. If a soluble base releases hydroxide ions (OH‾) it’s called an alkali. But what’s the strongest base in the world? This Everyday chemistry article explores alkalis we use in daily life, as well as superbases like the Proton Sponge and tert-butyllithium. You won’t find this superbase in a science class though because tert-butyllithium is so reactive it spontaneously bursts into flames on contact with air.
