Defining and Teaching pH Richard F. Burton
At an elementary level, pH and the algebra of equilibria can be simply and correctly taught, without logarithms, in terms of the modern, operationally-defined pH scale that underlies laboratory measurement and relates to activities.

Chemical queries. Especially for introductory chemistry teachers Young, J. A.; Malik, J. G.
(1) Is there such a thing as a negative pH value? Or one above 14? (2) What is entropy, in terms a beginner may understand? (3) On calculating the molecular weight of a solute from concentration and freezing point depression.
