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. 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?.

Zhang. Shana . Zucker. What is an acid? What is A Base?. Arrhenius. Acid- An acid is a substance that when dissolved increases H. +. concentration. Base- A base is a substance that when dissolved increases OH. Common Ion Effect. Learning Outcomes and . Prereqs. Pre-. reqs. :. Identify how changing concentrations of reactants or products shift an equilibrium (Le . Chatelier’s. Principle). Learning Outcomes. 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?. Different definitions of acids and bases. Acids are proton donors (. Brønsted. Lowry definition). they generate H. 3. O. +. in water (Arrhenius definition). Bases are proton acceptors. they generate OH. Equilibria. Electrolytes. Acids and Bases (review). The Equilibrium Constant. Equilibrium Expressions. “. Special. ”. Equilibrium Expressions. Solubility Products. Common-Ion Effects. Weak Acids and Bases. 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. weak conjugate base. A buffer is . resistant to changes in . pH because it can neutralize any strong acid or base added to it. 2A-1 . (of . 14). SOLUTION EQUILIBRIA. A solution contains both HF and F. Naming Basic Acids. When identifying and naming acids, you are looking for two characteristics:. The compound/molecule will begin with hydrogen, H-. The number of following atoms will then determine the two ways of naming. 2009, Prentice-Hall, Inc.. 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.. Different definitions of acids and bases. Acids are proton donors (. Brønsted. Lowry definition). they generate H. 3. O. +. in water (Arrhenius definition). Bases are proton acceptors. they generate OH. 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 .
