Chapter 20 Notes: Part I Acids and Bases
What are some common acids? • Vinegar (acetic acid) • Carbonated drinks (carbonic and phosphoric acid) • Citrus fruits (citric acid) • Car battery (sulfuric acid)
What are some common bases? • Milk of magnesia (an antacid containing magnesium hydroxide) • Many cleaning products (ammonia, etc)
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
What properties do bases have? Bases tend to be: • Bitter tasting • Slippery feeling when touched • Able to neutralize an acid • Also electrolytes (in solution)
What is an acid? • An acid is a compound that produces hydrogen ions (H+) when dissolved in water. • The formula would be HaX, where X is any monatomic or polyatomic anion and a is the anion’s charge.
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
Naming an Acid • 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. • H2SO3 is sulfurous acid
Naming an Acid • 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. • H2SO4 is sulfuric acid
Naming an Acid Negative ion: Acid Name: _____ ide hydro___ic acid _____ ite _____ous acid _____ ate _____ic acid
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
