PPT-How do Acids and Bases React

with Metal Activity CAUTION This activity needs the teachers assistance Set the apparatus as shown in Fig Take about 5 mL of dilute sulphuric acid in a test tube and add a few pieces of zinc granules to it. 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. Topic 8.4. A. cids. w. hen a . STRONG. acid dissolves- all, or nearly all, of the acid molecules dissociate to produce H. +. . or H. 3. O. +. ions (reaction goes to “completion”). have a . very. 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. 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.. . 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 . Three Kinds of Mixtures. 1.
