PPT-Acids and Bases Day 2 A beaker of aqueous solution has a pH of 7.2 and the desired pH

A beaker of aqueous solution has a pH of 72 and the desired pH is 94 Should an acid or base be added Base because to increase the pH the H needs to be at a lower concentration Bases will either increase the OH. 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. _____ . is a chemical compound that increases the concentration of ________________ ions (H. +1. ), in aqueous solution. The hydrogen ions are attracted to the water molecules in an aqueous solution and form . . 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.. A. Naming Acids and Bases . 6.1 Theories of Acids and Bases. . Section 6: Acids & Bases. . Rules. 1. hydrogen becomes acid. 2. hydrogen becomes acid. 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.. The . Brønsted. -Lowry Definition of Acids and Bases. 1. . Acid. is a substance that can donate (or lose) a . proton. ; . Base. is a substance that can accept (or remove) a . proton. ..  . 1) . Hydrogen chloride, a very strong acid, transfer its proton to water.. 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. ”. 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. 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. Solute Concentrations, Molarity. Solution: . homogeneous mixture of two or more substances. Solute. : . the substance being dissolved. Solvent. : . the substance doing the dissolving. Concentration. . An introduction to the properties of acids, bases, and the pH scale. Complete the following table. Element. Atomic. #. Mass #. Protons. Electrons. Neutrons. Ion, Isotope, or Neutral?. 82. 209. 16. 18. 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 .
