The effect of concentration and temperature on the conductivity ratio of potassium chloride solutions to standard seawater of salinity 35 ‰(Cl 19.3740 ‰) |
| |
| Abstract: | The ratiosZ_{K,t}of electrical conductivities of potassium chloride (KCI) solutions of known concentration (K) to standard seawater at the same temperature have been measured at15degC and24degC for solutions withZ_{k,15}between 0.96 and 1.04. The "normal" concentration (N or K_{N}) givingZ_{N,15}= 1was found to beK_{N} = 32.4356gKCI/kg solution. The effect of temperature onZ_{N,t}was measured over the range15degC to30degC. Equations are given for KCI concentration as a function ofZ_{15}and the inverse function, forZ_{15}/Z_{24}as a function ofZ_{24}(to allow use of a laboratory salinometer for the KCI-seawater comparisons), andZ_{N,t}as a function of temperature. |
