Does salt boil water faster?
When salt is added, it makes it harder for the water molecules to escape from the pot and enter the gas phase, which happens when water boils, Giddings said. This gives salt water a higher boiling point, she said.
Is it OK to drink boiled water?
How Does Boiling Water Make It Safe to Drink? Boiling water makes it safe to drink in the event of some type of biological contamination. You can kill off bacteria and other organisms in a batch of water simply by bringing it a boil. Other types of pollutants, such as lead, are not so easily filtered out, however.
