PPT-Acids and Bases in Chemistry

Scientists use indicators to test if an unknown substance is an acid base or neutral substance The pH scale is used as an indicator The pH scale measures the substance on a value of 114 Any substance that measures a . 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. Acids/ BASES. Acids. When dissolved in water, it will . ionize . into positively charged hydronium ions (H. 3. O+) and negatively charged ions of some other element. . Bases. Also . known as an alkali. . The taste of lemons and lime, the bite of sourdough bread, and the tang of a tomato are all caused by acids. Acids may be defined as substances that produce H. +. ions in solution. Citric acid, acetic acid, and tartaric acid are shown here.. 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. Day 3. Naming Acids. Acids usually have H as the cation. . H. Cl. Acids are named depending on whether they are oxyacids (ternary acids) or non-oxyacids (binary acids). 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.. Definition: . An acid is a substance that produces H. . ions in solution. Properties of acids. Tastes sour. Corrosive: . eats . away at other materials. Causes burns and tissue . damage. Able to conduct electricity. 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. Mullany. Chemistry. Agenda. We are going to learn. Properties of acids and . bases. Acid and base nomenclature. What is an acid and what is a base?. What is another way of classifying an acid and a base?. 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.. An introduction to the properties of acids, bases, and the pH scale. Complete the following table.

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). 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 .
