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
