Hydrogen Ions and Acidity. Section 19.2. To test a diagnosis of diabetic coma, a doctor orders several tests, including the acidity of the patient’s blood. Results from this test will be expressed in units of . 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. Chemistry 1105. background. An extremely large class of reactions. Found in . Biochemistry – .

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.. 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..
