Comments on Corrections to Steam Conductivity Measurements

Source

Published conductivity correction curves for carbon dioxide and ammonia disagree. A new curve, based on stated equilibrium constants and ionic conductances, is compared with these. The corrections are tabulated over a range suitable for plotting a useful curve. To eliminate the gas correction, conductivity is frequently measured at the atmospheric boiling point. Erroneous impressions of purity obtained by this method result from: 1. Neglect of the relatively high conductivity of pure water at 100 C, 2. Use of too small a temperature coefficient in correcting the measurement to 25 C. Conductivity measured at 100 C is not necessarily free of gas correction; samples should be checked for gases and the appropriate correction made. The correction for ammonia at 100 C is given.
