After writing four editions of a comprehensive analytical chemistry textbook, I set out to write a lower-level, abbreviated textbook. I needed to eliminate half the content of the comprehensive book and decrease mathematical demand. In agreement with Prof. Hawkes, I eliminated titration curve calculations for EDTA and redox reactions, but I retained acid–base titration curves. There are more important subjects for a student whose only formal exposure to analytical chemistry will be this one course and whose primary interest is likely to be outside of chemistry (such as life sciences). Surely, separation techniques are more important than calculating titration curves. The empirical result of my experiment in the first edition of Exploring Chemical Analysis (1) was a resounding cry from users to include EDTA and redox titration calculations—which I did in subsequent editions.
