Textbook Question
Chapter 10, Problem 27E
The surface tension and viscosity of water at several different temperatures are given in this table.
| Water | Surface Tension (mN/m) | Viscosity (mPa s) |
| 0 °C | 75.6 | 1.79 |
| 20 °C | 72.8 | 1.00 |
| 60 °C | 66.2 | 0.47 |
| 100 °C | 58.9 | 0.28 |
(a) As temperature increases, what happens to the surface tension of water? Explain why this occurs, in terms of molecular interactions and the effect of changing temperature.
(b) As temperature increases, what happens to the viscosity of water? Explain why this occurs, in terms of molecular interactions and the effect of changing temperature.

Explain why acid chlorides are more reactive than amides in reactions with nucleophiles.
Calculating the pH of a weak base titrated with a strong acid
An analytical chemist is titrating 101.7 mL of a 0.3500M solution of piperidine (C5H10NH) with a 0.05700M solution of HClO4. The pK of piperidine is 2.89.
Calculate the pH of the base solution after the chemist has added 682.9 mL of the HClO solution to it.
4
Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HClO solution added.
