Question
Chapter 6, Problem 6.77PAE
Interpretation Introduction
Interpretation:
The p and d orbitals are sometimes referred to as directional. This terminology should be explained by contrasting p and d orbitals with s orbitals.
Concept introduction:
Atomic orbitals describe where the electron is likely to be found.
- The s orbital is spherical in shape with nucleus at its center.
- The p and d orbitals are dumbbell shaped with opposite lobes carrying opposite signs.

Calculating the pH of a weak base titrated with a strong acid
An analytical chemist is titrating 241.7 mL of a 0.4900M solution of methylamine (CH3NH2) with a 0.7800M solution of HNO3. The pK of methylamine is
3.36. Calculate the pH of the base solution after the chemist has added 17.7 mL of the HNO3 solution to it.
Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO3 solution added.
