Lesson 10 AcidBase Titrations PART I w hat is a titration h ow is it performed w hat tools are needed PART II Perform Titration calculations A titration is a neutralization reaction . Dr. Harris. Ch. 21 . Suggested HW. : . Ch. 21: 1, 13, 29. Buffers. Solutions that contain both a weak acid and its conjugate base are called . buffers. . . Buffers have the unique ability to . resist sharp changes in pH. Definitions . Strong Acids. HCl. HBr. HI. HNO. 3. HClO. 4. H. 2. SO. 4. Acid: a species that supplies H. +. ions to water. Strong acid: an acid that completely ionizes in water forming an H. +. ion and an anion. Titration. Acid–Base Titration. The concentration of a weak acid or a weak base in water is difficult – if not impossible – to measure directly.. But we can calculate the concentration from the results of titration.. What did one titration tell the other?  . Let's meet at the endpoint.. Why are chemists great for solving problems?   . They have all the solutions. Titration. A lab procedure by which the concentration of acidic or alkaline solutions are examined and determined. of Salts. Acid-Base Properties of Salts. Type of Salt. Examples. Comment. pH of solution. Cation is from a strong base, anion from a strong acid. KCl, KNO. 3. NaCl. NaNO. 3. Both ions are neutral. Neutral. Prof. Tahir . Shafi. Why should we know about acid base disorders. What are acid base disorders. How to interpret acid base disorder. How to establish the cause. Why to worry about acid base disorders. 11-. 1. Activity: Precipitation Reactions. When a solution of lead(II) nitrate is mixed with a solution of potassium chromate, a yellow precipitate forms according to the equation:. Pb(NO. 3. ). 2. (. Lecture Presentation. James F. Kirby. Quinnipiac University. Hamden, CT. © 20. 15. Pearson Education, Inc.. 16.1 & 16.2 Some . Definitions. Arrhenius. An acid is a substance that, when dissolved in water, increases the concentration of hydrogen ions.. For cells to function optimally, . a steady balance . between the acids and the bases . is necessary.. Acid-base balance represents homeostasis of hydrogen (H+) ion . concentration in . body fluids. . Just a few reminders. What makes an acid an acid?. A . Bronsted. -Lowry Acid is a compound that donates a proton (a hydrogen ion with a positive charge, H. +. ). Think of the standard acids that are commonly mentioned in Gen . Strong Acids. HCl. HBr. HI. HNO. 3. HClO. 4. H. 2. SO. 4. Acid: a species that supplies H. +. ions to water. Strong acid: an acid that completely ionizes in water forming an H. +. ion and an anion. .. Acid-Base Titration. .. المحاضرة الثانية للجزء العملي. . . Acid-Base Titration. . Analytical chemistry. : is the analysis of material samples to understanding of their chemical composition and structure. It has a wide range of monitoring pollution in the environment, development of new materials, and drug manufacture.. REDOX AND POTENTIOMETRIC TITRATIONS. WE WILL LEARN FROM THIS CHAPTER:. ● . Balancing . redox. reactions . ● Calculating the reaction equilibrium constant from standard potentials. ● Calculating . This lecture presents the basic concepts of pharmaceutical inorganic chemistry with emphasis on the description, mechanisms and uses of various pharmaceutical products which are clinically used to correct various body disorders. The major topics to be covered are acids and bases, intra and extra cellular electrolytes, the gastrointestinal agents and topical agents frequently employed in the conversion of drugs to chemical forms convenient to their product formulations..
