Presentation Transcript

  1. Welcome back!!!! • Write the formula for the following: • Lithium Iodide • Potassium hydroxide • Magnesium oxide • Name the following compounds: • Na2O • MgCl2 • CaSO4 • What is a binary compound?

  2. Acids and Bases Unit 10, Day 1 Kimrey 2 January 2013

  3. Objectives • Describe properties of acids and bases. • Name acids given a formula • Write the formula of an acid given the name

  4. Poster Presentation • Get into the groups that you were in to make your acid base posters. • Take 5-10 minutes to put any finishing touches on the poster and decide how you’re going to present. • Come up and present your poster. Everyone must speak at least once! • Make sure to take notes! These will be your notes for acid base properties!

  5. Acids • Proton (H+) donor OR increases the concentration of hydronium (H3O+) ions • Formulas start with Hydrogen • pH less than 7 • Properties • Sour taste • React with metals to produce H2 • Reacts with bases to produce a salt and water. • Changes Phenolphthalein clear • Common Acids • Acetic Acid (Vinegar) • Sulfuric Acid (Battery Acid) • Citric Acid (Lemon Juice/Orange Juice/Lime Juice)

  6. Bases • Proton (H+) acceptor OR increases the concentration of hydroxide (OH-) ions • Formulas generally end in -OH • pH greater than 7 • Properties • Bitter taste • Feel Slippery/Soapy • Reacts with acids to produce a salt and water. • Changes Phenolphthalein pink • Common bases • Sodium Hydroxide (Drano) • Magnesium Hydroxide (Milk of Magnesia/Antacid) • Sodium Hypochlorite (Bleach)

  7. Naming Acids • There are two types of acids: • Oxyacids • Binary Acids • The type of acid determines how it will be named.

  8. Oxyacids • Contain Polyatomic Ions (will have more than two elements!) • Notice polyatomic ions generally end in either –ate or –ite. • If the polyatomic ends in –ate change the –ate to –icand add acid to the name. • Ex. H2SO4 • If the polyatomic ands in –ite change the –ite to –ous and add acid to the name • Ex. HClO2

  9. Example • Name the following Oxyacids: • HClO3 • H2SO3 • H2CO3 • HNO3 • Write the formula for: • Chlorous acid • Sulfic acid • Nitrous acid

  10. Binary Acids • Contain ONLY two elements!! • Take the root word of the anion (negative ion) and place it into the pattern of hydro_______-icacid • Ex. HCl

  11. Example • Name the following binary acids: • HI • HBr • Write the formula for the following binary acids: • Hydrochloric acid • Hydrofluoric acid

  12. Mixed Examples • Write the formula or name of the following acids: • Acetic Acid • HNO3 • Hydrofluoric acid • H2SO4 • Sulfous acid • HBr

  13. What did you learn today?? • Acids exist at what pH range? • Bases have what taste? • What happens when you mix an acid and a base? • Name the following: • HCl • HClO • Write the formula for the following: • Hydroiodic acid • Chromic acid
