PPT-Unit 8: Acids & Bases

Unit 8 Acids amp Bases PART 1 AcidBase Theory amp Properties I hereby define acids as compounds of oxygen and a nonmetal 1777 In fact I just named the newly discovered gas oxygen which means acidformer. Chemistry . Acids and Bases. Properties and pH. Chemical Warfare!. What is an Acid?. 3 Major Definitions: Arrhenius, Bronsted-Lowry, and Lewis.. Arrhenius and Bronsted-Lowry say an acid is:. A proton donor. 1. What are . acids. and how do they taste like?. What . acids. or . acidic . solutions. do you know?. What are . acids. and how do they taste like?. Taste: . sour, tart, tangy. What are . bases. Some Important Acids. (All acids have H atoms). Properties of Acids. Sour Taste. Reacts with Metals (Produce Hydrogen Gas). Reacts with Carbonates (Produce CO2). Turn Litmus Paper Red. Natural Indicators. Acid and Base Notes. I can distinguish between an acid and a base.. I can list the characteristics of an acid and a base.. I can name acids.. I can name bases.. What do you think an acid is?. Give an example of an acid.. Different definitions of acids and bases. Acids are proton donors (. Brønsted. Lowry definition). they generate H. 3. O. +. in water (Arrhenius definition). Bases are proton acceptors. they generate OH. p. 191-195. Anything about the pH scale?. Alkaline is another name for a base.. acid/base intro video. What can you tell me about acids and bases?. 1.2 Acids and Bases. pH scale- . indicates the acidity of a solution. Chapter 8.1. Objectives. Describe the ionization of strong acids in water and the dissociation of strong bases in water.. Distinguish between solutions of weak acids or bases and solutions of strong acids or bases.. What is an Acid?. A solution with an excess of H. +1. ions. How do we know that a chemical is an acid?. Most Acids start with an ‘H’ in their chemical formula. What are the properties of an Acid?. AP Chemistry, Mr. Guerrero. Acids. :. Sour taste. Turn litmus . red. Electrolytes- form ions in water. Corrosive-cause chemical burns to skin. React w/ metals to produce salt and H. 2. gas. . HX M . Acids are all around us.. Foods like lemons, limes, and oranges contain acidic compounds.. When wine is oxidized, it becomes acetic acid.. Our muscles produce lactic acid.. Our stomach uses hydrochloric acid to break down food.. Chemistry. Jacqueline P. Hancock, B.S., . M.Ed. Acid-Base Theories. Bracken Cave, near San Antonio, Texas, is home to twenty to forty million bats. Visitors to the cave must protect themselves from the dangerous levels of ammonia in the cave. Ammonia is a byproduct of the bats’ urine. You will learn why ammonia is considered a base.. . Acids and their properties. An acid is any compound that increases the number of . hydronium . ions. . Hydronium forms when and H separates from an acid and bonds with water = H. 3. O. . Acids have a . …. .. Acids & Bases are Based on WATER!. Depending on the amount of H+ or OH- ions, the “water” becomes either acidic or basic (aka alkaline). The pH scale determines the strength of the acid/base. Review!. What is an electrolyte?. What are examples? . Aim # 1 How do we define acids and bases?. Acidity:. . measure . of the hydrogen (H. +. ), hydronium (H. 3. O. +. )ion concentration of a . solution. Dissolve in solution to produce ions. .
