PPT-Acids and Bases Chapter 16

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. 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 . 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.. 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. 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. 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. .

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.” 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. Acid Base Equations. General Form of Dissociation. Acid.

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 .
