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. 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. ”. Properties of Acids. They taste . sour. (don’t try this at home).. They can . conduct electricity. .. Can be strong or weak electrolytes in aqueous solution. React with metals. to form H. 2. 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.. 1. Properties of Acids (w/ an example of an acid) [green, no dot]. Properties of . Bases (. (w/ an example of . a base) [green, w/dot]. Similarities between Acid & Bases [yellow]. Types of Acids (Monoprotic, diprotic, Triprotic) w/ example of each [red]. 10.1. Acids and Bases. 2. Acids. Arrhenius acids . produce H. . ions in water. H. 2. O. . H. Cl(. g. ) . H. . (. aq. ) Cl. . (. aq. ). are electrolytes. have a sour taste . 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. Acid Base Equations. General Form of Dissociation. Acid. HA .  H. + . + A. - . or. H. 2. O + . A .  H. + . + . AOH. -. Base. BOH  B. + . + OH. - . or. . H. 2. O . + . B .  . 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 .
