How does steam affect ionic conductivity?

Steam can significantly impact ionic conductivity based on various experimental findings. When steam is injected into sand saturated with a saline solution, the electrical conductivity initially decreases due to dilution of the solution, then peaks just before the steam front arrives, and finally drops significantly as the steam front passes through, leading to a decrease in saturation and dilution of the liquid phase. The quality of the injected steam plays a crucial role in conductivity changes, with low-quality steam resulting in a net decrease in conductivity, while high-quality steam causes a drop followed by an increase to an equilibrium value, likely due to the formation of a dilution bank that temporarily decreases local salinity. Additionally, the electrical conductivity of NaCl in steam varies with steam densities, indicating that steam density influences the behavior of electrolytes like sodium chloride.Are electric vehicle battery fires more likely if a battery is degraded?
