Problems Contents

These topics cause controversy in Chemistry teaching from time to time: some are treated incorrectly in textbooks, and some are simply difficult to get hold of.

Contents of the Problems pages:

	Physical: The solubility of ionic compounds is not governed by enthalpy changes alone. The pH of sulphuric acid is nearly that of a monobasic acid of the same concentration. Neutrality is not pH 7 The buffer action of amino acids Electrode potentials in copper. The nature of intermolecular forces.
	Inorganic: Aquo ions and hydroxide precipitates in transition-metal chemistry. Oxides and hydroxides. (Peter Hughes, Westminster School.) Aluminium chloride is not dimeric at ordinary temperatures...
	Organic: Will o'the Wisp - burning methane? The structure of benzene. The hydrolysis of halogeno compounds and of carbon tetrachloride and silicon tetrachloride.
