(1980) Gapon Coefficient and the Exchangeable Sodium
tential sodium hazard in irrigated soils (U S Salinity Lab , 1954) However, it contains SAR*, instead of SAR = Nar/fCar]*4, which is based on total molar concentrations, and KG instead of the traditional Gapon selectivity coefficient Although ESP values computed from Eq [2] are accurate to within 20 , the equation consistently un
Apparent molar volumes and viscosity B-coefficients of sodium
A- coefficient reflects solutesolute interaction-9 and the B-coefficient reflect the solute-solvent interactions 4 RESULTS AND DISCUSSION The values of the densities (ρ) and apparent molar volumes (ф) of sodium salicylate solution in NS, DNS, RL and pure water at 298 15, 303 15, 308 15, 310 15 and 310 15K temperature are shown in Table 1
