| Pg 77, Ch 3 | Problem 3-25. Part a is for aqueous ethanol, not glycerol. Answers in back are switched for a and c. | MK | ||
| Pg 172, Ch 7 | URL for dataset in Web Works has changed. Click link at right to view correction at bottom of this page. | Norris Data Link | ||
| Pg 225, Ch 10 | Example 10-4. Expression is correct for solution containing NaNO3, not NaCl. | MK | ||
| Page 228, Ch 10 | Line 2. Assumption that [H3O+] << 2[Mg2+] in eqn 10-8. Incorrect value for 2[Mg2+]. | 4.1 x 10^-11 <<1.6 x 10^-4 | 4.1 x 10^-11 << 2.4 x 10^-4 | MK |
| Page 499, Ch 19 | Operational definition of pH The equations preceding eqn 19-24 are lacking a negative sign. |
pHs = (Es - K)/0.0592 pHu = (Eu - K)/0.0592 |
pHs = -(Es - K)/0.0592 pHu = -(Eu - K)/0.0592 |

| A-3 in Appendix 2 | Ka1 for carbonic acid | 1.5 x 10^-4 | 4.57 x 10^-7 | |
| A-28 | Incomplete expression for 10-4(a) | 0.10 = ... | add [PO4^3-] to rhs | MK |
| A-28 | Expression for 10-4(e) is approximate, is not strictly an exact mass balance equation. | MK |

| 3-19 | Superscript error in concentration of sulfate. Final result is OK. | 2.87 x 10^-2 | 2.87 x 10^-3 | MK |
| 3-21f | Incorrrect conversion factor. Numerical result OK. | 1000 mL/L | 1000 mmol/mol | RAC F05 |
| 3-29c | Value used for [K+] is different from value given. Result given for mass of reagent corresponds to incorrect concentration. For [K+] = 0.0825, mass of K4Fe(CN)6 = 3.04 g. | MK | ||
| 3-33b | HClO4 is given as a reactant, but in part b it is referred to as HCl. This should be HClO4. In fact, either HClO4 or HCl will react in identical fashion with Na2CO3. | RAC F05 | ||
| 4-11e | The solubility of Th(OH)4 is [OH]/4. | S = 9.4E-5 mol/L | AJ Su07 | |
| 4-15b | Error in charge. | Ce2+ | Ce3+ | MK |
| 6-8a | Calcuation of CV has misprint for value of y. Calucated results are correct and correspond to the correct value of y. | 1.374 x 10^-9 | 1.374 x 10^-8 | SG S06 |
| 7-15 | Incorrect value for N1 used in final expression to calculate Student's t. Final result OK Correct value of N1 = 4. | MK | ||
| 10-8 | Incorrect exponent for K1K2 | 1.25 x 10^-21 | MK | |
| 10-11 | Incorrect value for K1 for carbonic acid | 1.5 x 10^-4 | 4. x 10^-7 | MK |
