Consider the titration of a generic weak acid HA with a strong base that gives the following titration curve:On the curve, indicate the points that correspond to the following: a. the stoichiometric (equivalence) point b. the region with maximum buffering c. pH pKa d. pH depends only on [HA] e. pH depends only on [A] f. pH depends only on the amount of excess strong base added
Chapter 2: The QuantumMechanical Model of an Atom Most of the atom’s volume is occupied by electrons The size of an atom depends on its electrons An atom’s electrons determine many of its chemical and physical properties Quantum particle like electrons can be in two different states at the same time Quantummechanical model explains the strange behavior of electrons, describes electrons as they exist within atoms, and determine the chemical and physical properties of elements The Nature of Light Light is found to have many characteristics in common with electrons such as wave particle duality of light The Wave Nature of Light Light is electromagnetic radiation, which is a type of energy embodied in oscil
