Acids and Bases Quiz Study Guide

Chapter 16

[Note: Programmable and graphing calculators may be used if there are no formulas or data that will help you with this quiz.]

KNOW THE FOLLOWING CONCEPTS:

• definitions of acids and bases (Arrhenius, Brønsted-Lowry, Lewis)
• strong vs. weak (when describing acids and bases)
• difference between strong acid and high concentration
• bases and their conjugate acids
• acids and their conjugate bases
• pH and pOH of acidic, neutral, and basic solutions
• pH + pOH = 14
• [H+] and [OH] of acidic, neutral, and basic solutions
• Kw = [H+][OH] = 10-14
• equilibrium in solutions of weak acids and bases
• how to dilute the concentration of a solution
• titration: endpoint, titrant, equivalence point, etc.
• neutralization reactions
• acid-base indicators
• molarity
• what buffers are made of
• how buffers work
• Henderson-Hasselbalch equation for the pH of buffers
• write expressions for Ka and Kb
• Ka and Kb are only used for weak acids / bases

BE ABLE TO ANSWER PROBLEMS INVOLVING:

• classify a formula as a strong acid, strong base, weak acid, or weak base
• pH and pOH – acids and bases / strong and weak
• pH of buffer solutions
• calculate [H+] from pH using [H+] = 10-pH
• calculate [OH] from pOH using [OH] = 10-pOH
• relate [H+] to [OH] using Kw = [H+][OH] = 10-14
• relate pH to pOH using pH + pOH = 14
