Standardized Test Preparation Chapter 14 Short Answer 10. How does a strong acid differ from a weak acid? Give one example of each. Answer: A strong acid is 100% ionized; a weak acid is less than 100% ionized. Possible strong acids are HCl, HI, HBr, HNO3, H2SO4, HClO4, and HClO3. With very few exceptions, any other acid will be a weak acid.

Chapter 14 Extended Response Standardized Test Preparation Chapter 14 Extended Response 12. Phosphoric acid, H3PO4, has three hydrogen atoms and is classified as a triprotic acid. Acetic acid, CH3COOH, has four hydrogen atoms and is classified as a monoprotic acid. Explain the difference, and justify your explanation by drawing the Lewis structure for both acids.

Chapter 14 Extended Response Standardized Test Preparation Chapter 14 Extended Response 12. Phosphoric acid, H3PO4, has three hydrogen atoms and is classified as a triprotic acid. Acetic acid, CH3COOH, has four hydrogen atoms and is classified as a monoprotic acid. Explain the difference, and justify your explanation by drawing the Lewis structure for both acids. Answer: Each of the H atoms in phosphoric acid is attached to an oxygen atom and can ionize. Only one of the H atoms in acetic acid is attached to an oxygen atom and can be ionized. The three H atoms bonded to C do not ionize; thus, acetic acid is a monoprotic acid.
