PPT-Acid-Base Reactions

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. Type 1: A metal combines with a nonmetal to form a binary salt.. Example: A piece of lithium metal is dropped into a container of nitrogen gas.. 6Li (s) + N. 2. (g) . → 2Li. 3. N (. aq. ). Synthesis Reactions. 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.. 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. Acid-Base chemistry & pH. Recognizing acid/base and conjugate base/acid. Calculation of pH, . pOH. , [H. 3. O. +. ], [OH. -. ]. Calculating pH for solutions of strong acids/base. Ionization constant: . Daley & . Daley.

Titration. In . this technique a known concentration of base (or acid) is slowly added to a solution of acid (or base. ).. The . analyte. - is the solutions being evaluated and is of unknown concentration.. Lecture 5. Introduction. A complex system of chemical buffers together with highly specialized mechanisms of the lungs and kidneys continuously work together to ensure a precise balance of water, electrolytes, and pH in both the intracellular and extracellular compartments of the human body. . 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. . Authors (University of Texas Austin): Chao Xie, Chunzhi Su, Manos Kapritsos, Yang Wang, Navid Yaghmazadeh, Lorenzo Alvisi, Prince Mahajan . Presented By:. Sharanya . Bathey. The tale of ACID…. Transaction. Velázquez. Research . Biology. What is pH. ?. pH. stands for the potential of Hydrogen. Is the concentration of hydrogen in a given substance.. [ ]. is the symbol for concentration.. In other words pH is . Acid-base balance.  . * Acids are electrolytes that release hydrogen ions (H+) when they are dissolved in water.. * Bases are electrolytes are release hydroxide ions (OH-) when they are dissolved in water..
