Аннотация
The electrical conductivity of sodium hydroxide–ammonium hydroxide solutions in the concentration ranges 1–3 M NaOH and 2–6 M NH4OH is studied in accordance with the content of the reagents in the solution and its temperature. It is shown that the electrical conductivity of the aforementioned system increases as the NaOH concentration increases, whereas, as the NH4OH concentration increases, the electrical conductivity decreases. The electrical conductivity of the system linearly is found to increase as the temperature of solution increases. This allows us to linearize the obtained dependences and to calculate the temperature coefficients of the electrical conductivity. The activation energy of the electrical conductivity is determined, which confirms the diffusion limitations of the charge transfer process in the system under study.
