3200ppm would have no affect on the freeze point of water, so your answer would be 32 degrees.
At what temperature does water frezes at 3000 feet
The boiling point is 3200 Kelvin.
3200 m = 3.2 km
The ideal salt level is between 2700-3400 ppm (parts per million) with 3200 ppm being optimal. Before adding salt to your pool, test the water to check your salt level.
