What Makes Things Alkali?

This video tutorial explores alkaline materials, their uses, and how they neutralize acids. It explains how to test for alkalis using litmus paper and defines alkalis as ionic compounds. The video covers various theories of bases, including Arrhenius, Lewis, and Bronsted-Lowry, and discusses equilibrium constants and the pH scale. It highlights the strength and safety of bases, noting that strong bases are reactive and corrosive, while organic alkalis are weaker.

Explain the Arrhenius definition of a base.

Why are strong bases considered dangerous?
