Reacts with Metals (Produce Hydrogen Gas). Reacts with Carbonates (Produce CO2). Turn Litmus Paper Red. Natural Indicators. 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. Weak acids only partially dissociate in water. . Hydrofluoric acid, HF, is the only halogen that forms a weak acid.. Learning Goal . Write equations for the dissociation of strong and weak acids; identify the direction of reaction.. 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.. 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). Topics 5 and 6 . May 4-6, . 2020. .
