1 What is the approximate pH of a solution that is a yellow in methyl red yellow in phenol red and yellow in alizarin yellow b yellow in methyl red red in phenol red and red in alizarin yellow 2. Acids turn blue litmus to red 2 Acids turn methyl orange to red Bases effect indicators 1 Bases turn red litmus to blue 2 Bases turn methy l orange to yellow 3 Bases turn phenolphthalein to purple Acids neutralize bases producing a salt and water Ba 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. 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. 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.. Taste. Acids taste sour. Foods. citrus fruits . yogurt and sour milk. carbonated beverages. vinegar. Acid. citric acid. lactic acid. carbonic acid. acetic acid. Bases taste bitter. Like soap. Touch. MEASUREMENT. REACTIONS. The sour and spicy tastes are properties of acidic substances. The bitter taste is a . property of basic . substances. ACIDS & BASES. INTRODUCTION. Your own body produces acids and strong bases. 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.. Explain the chemical composition of acids and bases, and explain the change of pH in neutralization reactions.. D12. I can differentiate between acids and bases.. Learning Target. When dissolved in water, they ionize (form ions). A special solution. Acids and bases are ALWAYS in a water solution.. Your body has water in it so they are always dangerous to living things.. Bases are just as dangerous as acids.. In low . concentrations. An introduction to the properties of acids, bases, and the pH scale. Complete the following table. Element. Atomic. #. Mass #. Protons. Electrons. Neutrons. Ion, Isotope, or Neutral?. 82. 209. 16. 18. Acids and Bases. Arrhenius definition. Bronsted-Lowry definition. pH. Strong vs weak acids. Neutralization reactions. Some Properties of Acids. Produce H. . (as H. 3. O. . ) ions in water (the hydronium ion is a hydrogen ion attached to a water molecule). Unit 8: Acids & Bases PART 1: Acid/Base Theory & 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 “acid-former.” Objectives. Relate the process of ionization to the formation of acids and bases. Explain qualities of acids and bases . Compare the acidity of substances, using the pH scale and pH indicators . Use molarity and titration to determine the concentration of an acid .
