20.500.12556/DKUM-68653 Vpliv skupnih ionov na prevodnost elektrolitskih mešanic The influence of common ions on the conductivity of electrolytic mixtures S konduktometrično metodo smo v termostatirani celici merili vpliv iona na prevodnost elektrolitov pri 25℃. Za merjenje prevodnosti smo pripravili raztopine NaCl, KCl in NaNO3 s koncentacijo od 0,001 do 0,01 mol/L. Mešanice soli smo pripravili tako, da je bila skupna koncentracija vedno 0,01 mol/L. Spreminjali smo sestavo mešanic in merili spremembe prevodnosti. V raztopini NaCl in KCl smo preučevali vpliv skupnega aniona, v NaCl in NaNO3 vpliv skupnega kationa, v mešanici KCl in NaNO3 pa ni skupnega iona, ki bi vplival na skupno prevodnost. S pomočjo grafov čistih elektrolitov smo potrdili Kohlrausch-ev zakon. Molske prevodnosti mešanic se gibljejo med vrednostmi čistih raztopin in so odvisne od sestave elektrolitske mešanice in od gibljivosti skupnih ionov. Using the conductometric method, the ion influence on the electrolyte conductivity at 25°C was measured in a thermostated cell. To measure the conductivity, solutions of NaCl, KCl and NaNO3 were prepared with a concentration of 0.001 to 0.01 mol / L. The salt mixtures were prepared in such a way that the total concentration was always 0.01 mol / L. We changed the composition of the mixtures and measured the changes in conductivity. We studied the effect of the common anions in the NaCl and KCl solution, and the effect of the common cations in the NaCl and NaNO3 solution. There were no common ions in the KCl and NaNO3 mixture that would affect total conductivity. Using the graphs of pure electrolytes we confirmed Kohlrausch's law. The molar conductivity of the mixtures varies between the values of the pure solutions and depends on the composition of the electrolytic mixture and the mobility of the common ions. prevodnost elektrolitov skupni ion Kohlrausch-ev zakon molska prevodnost conductivity of electrolyte common ion Kohlrausch's law molar conductivity true true false [L.
