 Write the formula for the following: ◦ Lithium Iodide ◦ Potassium hydroxide ◦ Magnesium oxide  Name the following compounds: ◦ Na 2 O ◦ MgCl 2 ◦ CaSO 4  What is a binary compound?

Unit 10, Day 1 Kimrey 2 January 2013

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

 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!

 Proton (H + ) donor OR increases the concentration of hydronium (H 3 O + ) ions  Formulas start with Hydrogen  pH less than 7  Properties ◦ Sour taste ◦ React with metals to produce H 2 ◦ 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)

 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)

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

 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 –ic and add acid to the name. ◦ Ex. H 2 SO 4  If the polyatomic ands in –ite change the –ite to –ous and add acid to the name ◦ Ex. HClO 2

 Name the following Oxyacids:  HClO 3  H 2 SO 3  H 2 CO 3  HNO 3  Write the formula for:  Chlorous acid  Sulfic acid  Nitrous acid

 Contain ONLY two elements!!  Take the root word of the anion (negative ion) and place it into the pattern of hydro_______-ic acid  Ex. HCl

 Name the following binary acids:  HI  HBr  Write the formula for the following binary acids:  Hydrochloric acid  Hydrofluoric acid

 Write the formula or name of the following acids:  Acetic Acid  HNO 3  Hydrofluoric acid  H 2 SO 4  Sulfous acid  HBr

 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
