What happened when you blew on the ice and salt mixture​

Adding salt to ice or ice water actually lowers the temperature and makes it colder than the regular freezing temperature for water, 32 degrees F. The mixture soaks up heat from the surrounding skin cells, causing a second- or third-degree burn similar to frostbite

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
