1. Chapter 20 Notes: Part I Acids and Bases

2. What are some common acids? Vinegar (acetic acid) Carbonated drinks (carbonic and phosphoric acid) Citrus fruits (citric acid) Car battery (sulfuric acid)

3. What are some common bases? Milk of magnesia (an antacid containing magnesium hydroxide) Many cleaning products (ammonia, etc)

4. What properties do acids have? Acids tend to be: Tart or sour tasting Electrolytes (in solution) They can cause chemical dyes (called indicators) to change colors

5. What properties do bases have? Bases tend to be: Bitter tasting Slippery feeling when touched Able to neutralize an acid Also electrolytes (in solution)

6. What is an acid? An acid is a compound that produces hydrogen ions (H + ) when dissolved in water. The formula would be H a X, where X is any monatomic or polyatomic anion and a is the anion’s charge.

7. Naming an Acid When the name of the anion (X) ends in –ide, the name begins with hydro-, then the stem of the anion, then the name ends with –ic acid instead of -ide. ex) HCl is hydrochloric acid

8. When the name of the ion ends in –ite, then the name would be the stem of the anion and the suffix –ous acid instead of –ite. H 2 SO 3 is sulfurous acid Naming an Acid

9. When the name of the ion ends in –ate, then the name would be the stem of the anion and the suffix –ic acid instead of-ate. H 2 SO 4 is sulfuric acid Naming an Acid

10. Negative ion:Acid Name: _____ idehydro___ic acid _____ ite_____ous acid _____ ate_____ic acid

11. What is a base? A base is a compound that produces hydroxide (OH - ) ions when in solution. Bases are named the same way that an ionic compound would be named. NaOH is sodium Hydroxide
