A buffer is a solution that is a mixture of either a weak acid and its conjugate base or a weak base and its conjugate acid. When strong acids or strong bases are added, buffers either accept protons when they are in excess or donate protons when they have been depleted to minimize changes in pH. Which of the statements correctly describe the properties of a buffer? Select one or more: a. The weak base of an alkaline buffer will...

General Chemistry II Part 3. Now let's consider the effect of structure on acid-base properties: There are two main factors that determine whether a molecule containing X-H bond will behave as a Bronsted-Lowry acid and donate a proton: the strength of the bond and the polarity of the bond. On one hand, the stronger the X-H bond, the lower the molecule's tendency to donate the proton. On the other hand, the more polar the X-H bond, the higher the molecules...

General Chemistry II Workshop 3: Acid-Base Equilibria (10 pts total) In today's workshop we will explore two classes of compounds known as acids and bases. Acids were first identified as compounds that taste sour while bases were first identified as compounds that feel slippery and taste bitter. Today there are 3 prevailing theories that define acids and bases. We will spend most of our time...
