FIG. 4. Conductivity of nitrating mixtures at various temperatures
(Swinarski and Piotrowski [52]).
Swinarski and Piotrowski also examined the conductivity of pure nitric and
sulphuric acids as a function of temperature (Fig. 5). The curve for nitric acid
has a maximum at 20°C. At 40°C the conductivity falls.
