PPT-Acids and Bases Unit What is an Acid?

A solution with an excess of H 1 ions How do we know that a chemical is an acid Most Acids start with an H in their chemical formula What are the properties of an Acid Tastes sour Turns blue litmus paper red. 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. What is an Acid?. A solution with an excess of H. +1. ions. How do we know that a chemical is an acid?. Most Acids start with an ‘H’ in their chemical formula. What are the properties of an Acid?. 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. 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.” 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. Review!. What is an electrolyte?. What are examples? . Aim # 1 How do we define acids and bases?. Acidity:. . measure . of the hydrogen (H. +. ), hydronium (H. 3. O. +. )ion concentration of a . solution. Dissolve in solution to produce ions. . 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 .
