Abstract
The relative humidity-temperature relationships have been determined in air in equilibrium with saturated salt solutions of lithium chloride. LiCl. H<sub>2</sub>O; magnesium chloride, MgCl<sub>2</sub>. 6H<sub>2</sub> O; sodium dichromate, Na<sub>2</sub>Cr<sub>2</sub>O<sub>7</sub>.2H<sub>2</sub>O; magnesium nitrate, Mg(NO<sub>3</sub>)<sub>2</sub>. 6H<sub>2</sub>O; sodium chloride, NaCl; ammonium sulfate, (NH<sub>4</sub>)<sub>2</sub>SO<sub>4</sub>; potassium nitrate, KNO<sub>3</sub>; and potassium sulfate, K<sub>2</sub>SO<sub>4</sub>, over a temperature range of 0° to 50°C, using the dewpoint method. The relative humidity is a continuous function of temperature, and, except for sodium chloride, is monotonic. The curve for sodium chloride increases from 74. 9 percent relative humidity at 0°C to a maximum of 75.6 percent at 30°C and then gradually decreases to 74.7 percent. The maximum change in relative humidity with temperature, about 15 percent relative humidity as the temperature increases from 0° to 50°C, occurs with saturated salt solutions of sodium dichromate and magnesium nitrate.
