Lewis Acids and Bases

[404651793]

When any question about acids and bases are posed, how do we know if the acid or base is strong or weak if not mentioned? Is there a specific kind of formula for this?

There are certain strong acids and bases that you should memorize and there's a list in the course reader on page 151. Acids such as HCL, HBr, HI are strong. Alkali metal hydroxides (LiOH, NaOH, KOH) and heavier alkaline earth metal hydroxides are strong bases. Organic compounds are usually weak.
