PPT-HOW STRONG ARE ACID OR BASE SOLUTIONS?

We know how acidbase indicators can be used to distinguish between an acid and a base We have also learnt about dilution and decrease in concentration of H or OH ions . Electronegativity of the atom attached to H the more EN the attached atom the more acidic the molecule C N O F relative electronegativity CH NH HO F relative stability of conjugate bases CH NH H O HF relative acidity 1 Charged vs noncharged 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.. 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. Lets walk through them all together:. Strong/Strong Titration Calculations. If 100. mL of a Mg(OH). 2. solution is titrated with 25.0mL of 2.00 M . HCl. …... What is the pH at the equivalence point?. 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: . Principles of Chemical Reactivity: . The Chemistry of Acids and Bases. In Chapter 3, you were introduced to two definitions of acids and bases: the Arrhenius and the Brønsted–Lowry definition.. Arrhenius acid: Any substance that when dissolved in water increases the concentration of hydrogen ions, H. Building a strong customer base is viable for any and every business today. Today, every business runs after attracting new customers and don't pay much heed on existing ones. However, with a good customer base, you can get new customers as well as maintain good terms with your existing ones. Go through the ppt to learn more about what is customer base and how to retain and enlarge the customer base. Done By:. Assistant Lecturer . Zeina. . Dawood. Assistant Lecturer . Sura. . Zuhair.
