Professional Hittite Engineer Exam Calculate the smallest limb diameter on a persimmon tree that will support a 10-pound possum.
Naming Acids and Bases:At the conclusion of our time together, you should be able to: List 3 properties of acids and bases Name a binary and oxy- (ternary) acid Name a base
6 Types Of Chemical Compounds • Binary ionic - metal ion – nonmetal ion • Binary molecular - two nonmetals • Ternary ionic - at least one ion is a polyatomic ion • Binary acid - H – nonmetal • Ternary acid - H – Polyatomic ion • Base - metal ion – OH
Acids & Bases • Their Properties
Properties of Acids • Taste sour • Itchy on skin, will burn if concentrated • Turns Blue litmus paper Red • Red litmus paper stays Red Reacts with Base - Neutralization: Acid + Base Salt + Water Ex: Vinegar, Citrus Fruit
Properties of Bases • Taste Bitter • Feel Slippery • Turns Red litmus paper Blue • Blue litmus paper stays Blue Reacts with Acid - Neutralization: Acid + Base Salt + Water Ex: Soap, Milk of Magnesia, Most Cleaners
Things You Can LearnFrom Your Dog!! When your loved one comes home, run to greet him/her. Eat with gusto to show your appreciation for the meal.
The Fourth Category Of Compounds Is Binary Acids. • These compounds begin with hydrogen since they are “acids”. • Attached to the hydrogen is a nonmetal ion • Hydrogen – nonmetal ion
What are Binary Acids? Binary means two elements Naming All binary acids follow the pattern as shown next:
Naming Binary Acids • Contain “H” and one other element (nonmetal) To Name: Hydro + second element name shortened (stem) + ic + acid Ex: HCl = Hydro chlorine – ine + ic acid Hydrochloric acid HF = Hydroflouric acid
Stem or root of nonmetal Prefix Suffix Hydro- < NM > -ic acid HCl is a binary acid – hydrogen - nonmetal HCl chlor acid Hydro ic Hydro iod ic acid HI Hydro sulfur ic acid H2S
The Fifth Category Of Compounds Is Ternary Acids. • These compounds begin with hydrogen since they are “acids”. • Attached to the hydrogen is a polyatomic ion • Hydrogen – polyatomic ion
New Element On The Periodic Table Element: Woman Symbol: Xx AtomicMass: 120 (More Or Less)
Before we name ternary acids lets learn some variations on the polyatomic ions… • The standard ions that you have memorized that end in – ate can be changed by adding or subtracting oxygens to form 3 more ions.
Let’s see what happens when we add or subtract oxygens… Perbromate Bromate Bromite Hypobromite
Let’s try it again… Persulfate Sulfate Sulfite Hyposulfite
Now let’s use this information to name ternary acids, acids with polyatomic ions… • The standard ions that you have memorized that end in – ate can be changed by adding or subtracting oxygens to form 3 more ions that can make 3 more acids.
Naming Ternary (Oxy)Acids (cont.) • Contain “H”, “O” and one more element To Name: Polyatomic ion “ate” “ic” + acid Ex: HNO3 =Nitr-ate ic + acid Nitric acid HClO3 = Chloric acid • An easy way to remember which goes with which… • “In the cafeteria, you ATE something ICky”
Naming Acids (cont.) • If the acid has one more oxygen than the base acid, the naming goes as follows: To Name: Per + Polyatomic ion “ate” “ic” + acid Ex: HNO4 = Per + Nitr-ate ic + acid Pernitric acid H2SO5 = Persulfuric acid
Naming Acids (cont.) • If the acid has one less oxygen than the base acid, the naming goes as follows: To Name: Polyatomic ion “ite” “ous” + acid Ex: HNO2 = Nitr-ite ous + acid Nitrous acid H2SO3 = Sulfurous acid
Naming Acids (cont.) • If the acid has two less oxygens than the base acid, the naming goes as follows: To Name: Hypo + Polyatomic ion “ite” “ous” + acid Ex: HNO = Hypo + nitr-ite ous + acid Hyponitrous acid HClO = Hypochlorous acid
New Element On The Periodic Table (cont.) PhysicalProperties of Xx: Generally round in form. Boils at nothing and may freeze anytime. Melts whenever treated properly. Very bitter if not used well. ChemicalProperties: Very active. Possesses strong affinity to gold, silver, platinum, and precious stones. Violent when left alone. Able to absorb great amount of exotic food. Turns slightly green when placed beside a better specimen. Ages rapidly.
Writing Acids This is a Ternary acid (does not begin with “hydro-”. Phosphoric acid H1+PO43- The “-ic” suffix indicates that the polyatomic ion in this acid has a suffix of “-ate” - phosphate Assume that hydrogen is +1 and balance the charges. H3PO4
Writing Acids (cont.) Hypochlorous acid This is a Ternary acid (does not begin with “hydro-”. H+1 ClO-1 The “-ous” suffix indicates that the polyatomic ion in this acid has a suffix of “-ite” – hypochlorite 1 less oxygen Hypo- means 1 more oxygen less HClO Assume that hydrogen is +1 and balance the charges.
New Element On The Periodic Table (cont.) Usage of Xx: Highly ornamental. An extremely good catalyst for disintegration of wealth. Probably the single most powerful income reducing agent known. Caution: Highly explosive in inexperienced hands.
Naming Bases • Name the metal first • Add hydroxide Ex: NaOH = Sodium hydroxide KOH = Potassium hydroxide
Practice Naming Bases Sodium hydroxide Iron (III) hydroxide Magnesium hydroxide Nickel (II) hydroxide Ammonium hydroxide
Naming Acids and Bases:At the conclusion of our time together, you should be able to: List 3 properties of acids and bases Name a binary and oxy- (ternary) acid Name a base
