  1. Chapter 19 Notes: Part IV Strong and Weak Acids/Bases

  2. Strong/Weak Acids and Bases • Whether an acid or base is considered strong is based on how much they dissociate, or break down into ions, when in solutions.

  3. Strong/Weak Acids • A strong acid is completely ionized in aqueous solution. • A weak acid is only partly ionized in aqueous solution. http://www.mhhe.com/physsci/chemistry/essentialchemistry/flash/acid13.swf

  4. Strong/Weak Bases A strong base is completely ionized in aqueous solution. A weak base is only partly ionized in aqueous solution.

  5. Strong acids include: • Binary acids: HCl, HBr, HI • Ternary acids: HNO3, HClO3, HClO4, H2SO4 • Strong bases include: • All hydroxideswith metals in the first two groups on the periodic table except Be and Mg.
